✅ Setting up the carburetor of a Goodluck chainsaw

Tools

A chainsaw is an indispensable tool both in the homestead and in the summer cottage. But even the most reliable “iron” assistant begins to mope, sometimes it won’t start, sometimes it stalls. There can be many reasons, both related to the quality of the fuel mixture and the engine.

There are a lot of nuances, we will not consider all of them in this article. Let's take a closer look at that part of the engine called the carburetor. And we will try to find the answer to the following questions: when is it necessary to adjust the carburetor of a chainsaw and, in fact, what is the scheme for such adjustment.

Chainsaw carburetor design

Before you start making adjustments, you need to know the structure and principle of operation of the carburetor. This will help avoid many “complications”. So, first, let's remember the principle of operation of an internal combustion engine. The cylinder contains fuel; when burned, it creates a small “explosion” which creates a lot of pressure. This pressure pushes the piston; the piston, when in motion, rotates the crankshaft. Ultimately, the pressure energy is converted into torque, which drives the chain through the sprocket.

During normal engine operation, it burns only up to 10 milligrams of fuel in each cycle. And the fuel mixture is prepared and supplied in the carburetor.

Thus, the purpose of the carburetor is to mix the combustible mixture with air in the required proportions. If these proportions are violated, engine operation is disrupted. For example, when mixing, little fuel is supplied, but on the contrary there is a lot of air, then such a mixture is called “lean”. And vice versa, if there is not enough air, but on the contrary there is a lot of fuel, then this is a supersaturated mixture. Both cases lead to malfunctions in the normal operation of the engine and require adjustment.

The carburetor consists of the following basic elements, and although the design may differ depending on the model, the structure and principle of operation are approximately the same:

the base of the carburetor is a tube, its characteristics reminiscent of a wind tunnel, through which air flows; — an air damper is located across the tube; by its position, it either increases the air flow or reduces it;
the tube has a narrowing - a diffuser, which increases the air flow speed exactly in the place where the fuel supply hole is located;
the fuel itself enters the air channel from the atomizer, into which it enters through a nozzle from the float chamber (indicated in the photo as a fuel needle);
the float chamber itself serves as a kind of reservoir, the purpose of which is to ensure a constant level of fuel at the entrance to the air channel.

The principle of operation of the carburetor is as follows. A fast flow of air flows through the air channel; its speed will also depend on the position of the damper. The float level provides the degree of opening of the fuel supply channel and depends on the position of the same air damper. The air flow, passing through the diffuser, picks up the incoming fuel and atomizes it. At this moment, a mixture is formed, which is sucked through the intake manifold into the cylinder.

In the float chamber the pressure level is approximately equal to atmospheric pressure, but in the air channel it is rarefied. Due to the pressure difference, fuel is sucked through the nozzle into the air channel. The more the air damper is open, the greater the air flow, and, accordingly, the more fuel flows. More fuel means engine speed increases.

This is the principle of operation of a carburetor. There may be nuances in its structure, but knowing how a simple carburetor works, you can always understand and determine the purpose of other elements.

In what cases is adjustment necessary?

In general, the need to adjust the carburetor of a Stihl chainsaw, or any other brand, arises quite rarely. Signs of a misadjusted carburetor are indicated by:

the engine starts and stalls, or does not start - in this case, the cause may be a “poor” fuel mixture;
fuel consumption has increased significantly and the amount of exhaust gases has increased (the fuel does not burn completely) - the cause may be a supersaturated mixture.

The adjustment itself goes wrong in very rare cases, namely:

when the fixation of the adjusting screws was broken, there are three in total. The cause may be vibration or damage to the protective cap. This is a fairly rare case if no one touched the screws.
in case of significant wear of the engine, namely the piston. Then the factory settings are not suitable. In this case, adjusting the carburetor of a Patriot chainsaw or another model can save the situation for a while. But here it’s time to think more about engine repairs than adjusting the carburetor of a Husqvarna chainsaw or the like;
the reason may be due to the formation of a blockage in the carburetor, the cause may be poor quality gasoline, damage to the air filter or scale. In this option, in addition to adjustment, disassembling and washing the carburetor is necessary.

Adjusting the chainsaw carburetor

Although quite rare, carburetor adjustment may still be required. Let us immediately note that not everything can be done on your own, unless you have a tachometer and at least once see with your own eyes how to do it correctly.

To adjust the carburetor of the Makita chainsaw, like most other models, there are three adjusting screws. Although some manufacturers carefully removed two of them, leaving only one for user experimentation. So, three screws, on the carburetor body they are indicated by the following letters:

L – this screw is used to adjust low engine speeds;
H – high speed adjustment;
T – for adjusting idle speed (this is left for experiments).

In general, carburetors are already adjusted by the manufacturer for optimal operation, and the screws are designed for more precise adjustment of the carburetor of Champion chainsaws and others, in difficult climatic conditions, such as high mountains, etc. Because the air is thinner there, the instrument requires more precise adjustments to operate. Under normal conditions this is not necessary.

About the manufacturer

The full name of the company is Goodluck Science & Technology Co. Its founding date can rightfully be considered 2001. The main direction of its activity is the production of equipment and tools, the specialization of which is site care. It is worth noting that the direct homeland of the manufacturer is China.

The company annually produces a huge number of chainsaws and electric saws, electric trimmers, lawn mowers, brush cutters, brush cutters, pumps (water) and other such equipment. Chainsaw or electric saw, which is better?

An important, one might even say the main advantage of the company’s products is that every part used in its production is made exclusively from high-quality material. Which, through numerous checks, meets all the necessary conditions and standards regarding safety and reliability.

Moreover, due to the fact that all of his equipment has a unique function, namely supplying oil on an automatic basis, the immediate life of the equipment is significantly extended.

In addition, the manufacturer has equipped its products with the highest power, minimal noise level, a fairly small weight category, as well as anti-vibration, which is a godsend for every owner of electrical equipment.

In addition, each individual product of the company has not only durability, but a modern design. The company is in rapid development every day, as absolutely everything, even minor details regarding the production of electrical equipment, are taken into account and improved. Just imagine, every year more than eight hundred models of various types come out of the manufacturer’s machine.

Carburetor design

A carburetor is a mechanism that is responsible for preparing a mixture of fuel and air, which is then supplied to the engine cylinder. Most chainsaws have very similar carburetors, so they are set up in the same way.

The main structural parts of a carburetor on a chainsaw:

Aluminium case. Aluminum is chosen as a material due to its low weight. Chainsaws are tools that constantly need to be held and carried, so reducing the weight of the tool is a very important task facing the manufacturer.
Diffuser and air damper, which are located at the inlet of the carburetor.
Jets are valves that provide dosage of fuel that is supplied to the carburetor.
The atomizer, which is responsible for injecting fuel into the chamber.
Fuel chamber.

Conclusion

To choose or not to choose Goodluck chainsaws is a personal matter. From the point of view of an independent expert, price and quality are well balanced. These saws are inexpensive, can be repaired and adjusted independently, which means they will find their users. Adjusting the carburetor is not difficult and can be done practically on your knees.

Chainsaws of the Goodluck brand are produced primarily for use at home and in the local area. Models of this brand are distinguished by excellent ergonomics, high operating speed, as well as low noise and vibration levels. Each Goodluck chainsaw is compact in size and light in weight. This allows you to confidently use any garden tool from this brand on trees, roofs and other hard-to-reach places.

Step-by-step disassembly instructions

The carburetor design of models of different brands is almost the same, so let’s take the Partner chainsaw as an example. We carefully remove each element and place it in order to make it easier to assemble later.

Carburetors of chainsaws from different manufacturers, if they differ, are not fundamentally different

We also carefully remove the gasoline hose, which the arrow points to.

We finally disconnect the carburetor, it is ready for adjustment. Its mechanism is quite complex, therefore, if further disassembly of the carburetor is required, you should remove the elements very carefully - they are small, so they can get lost.

The carburetor consists of many small parts, which should be laid out in order when disassembling

Characteristics

The maximum power of the Goodluck 4500 gasoline saw reaches 2 kW - 9000 rpm. This is an extremely high figure compared to many analogues, given the affordable price of the device. The 45 cm³ drive volume is enough to perform ordinary tasks in the house and garden. In addition, the 4500 supports the additional installation of a sawing set with a length of up to 50 cm.

This length is more than enough for everyday use. Moreover, installing a long chain will cost more.

The capacity of the fuel tank is more than 0.5 liters, the oil tank is 0.3. Fuel consumption is directly dependent on the conditions of use of the unit, the condition of the fuel pump and the correctness of the carburetor superstructure. With a full tank, the device can work for more than half an hour. During this period, you can cut about 0.5 m³ of firewood into small logs.

Whether you live in Dnipro or in another city, we deliver to any location in the country of Ukraine. It turns out that to buy a carburetor for a chainsaw, you just need to carefully read our article materials.

Fuel supply system repair

Fuel may not enter the cylinder for the following reasons:

Fuel filter is dirty. You should remove the fuel hose and check how the fuel flows. If the stream is weak, the filter may need to be cleaned. It is taken out through the filler hole of the fuel tank and cleaned; in case of severe contamination, it is replaced with a new one. As a preventative measure, it is recommended to replace the fuel filter once every three months.
Clogged breather (hole in the fuel tank cap). They also check by disconnecting the hose; if clogged, clean it with a needle.
Lack or insufficient fuel. There may be several reasons for the malfunction. The first reason is a clogged air filter. Air stops flowing into the carburetor in the required quantity, and therefore, due to the fuel mixture being too rich, engine operation is disrupted. The dirty filter is carefully removed, cleaned and rinsed in water, then dried and replaced.

Another reason is incorrect carburetor adjustment. Adjustment is made with three screws.

Timely replacement of the fuel filter guarantees a complete fuel supply

The fuel hose and choke actuator must fit tightly to the fittings

The throttle cable must be in place.

During work, you must use the instructions, otherwise you can only make things worse.

And the last reason is a violation of the integrity of the membrane or clogging of the carburetor channels.

To repair a carburetor yourself, you need to become familiar with all its parts.

All parts must be clean, dry and in good working order.

Adjusting the Goodluck 4500 Chainsaw

Do-it-yourself chainsaw carburetor adjustment

For an independent carburetor option, you need to familiarize yourself with its structure and understand the procedure for the work that is carried out to adjust the parts responsible for the proper functioning of the components of the device and parts close to it.

It is necessary to carefully handle items for the system option, and also to determine whether the set characteristics correspond to very acceptable values.

About the carburetor design

The carburetor serves to mix the flammable mixture with air while maintaining predetermined proportions. If clear doses are not followed, the proper operation of the engine is at risk. When a huge amount of air enters during mixing of the components, but there is not enough fuel, then such a mixture is considered “lean”.

Oversaturation should not be allowed, because with a larger amount of fuel compared to air, malfunctions or engine wear are also likely. Carburetor adjustment is needed not only before initial use, but also when any differences in its operation are detected. Before working with a chainsaw, do not forget to run it in.

Replacement of wear parts

If you do not replace wearing parts in a timely manner, their excessive wear will negatively affect the remaining components of the chainsaw. In particular, if the tire and drive sprocket are not changed in time, increased vibration will negatively affect the crankshaft bearings. The maximum working depth of the sprocket teeth should be 0.5 mm.

In practice, sprockets are often operated to a wear depth of 1 mm or more, without realizing that this leads to increased load on the crankshaft bearings and their accelerated failure. When 3-4 chains wear out, it is necessary to change the tire itself; by this time its wear reaches its maximum values.

The chainsaw bar wears especially badly in the area where cutting is done most frequently, usually the underside of the guide bar. When is it necessary to adjust a chainsaw carburetor? If chainsaw videos are about. To ensure uniform wear, each time the chain is replaced, the bar must be turned 180° relative to the horizontal axis.

When installing a new chain, a new drive sprocket must be installed. Since under normal load the service life of the drive sprocket is twice as long as the service life of the chain, it is advisable to use one sprocket for alternate operation of two chains. Thanks to this, the sprocket and chains wear out almost simultaneously.

Carburetor adjustment Goodluck 4500 and 5200

The carburetor on the Goodluck GL 5200 and 4500 chainsaws is a membrane carburetor with three adjustment screws. Each of which is responsible for operating the engine in a given range:

L – idling and low speed (mixture quality);

H – average and maximum (amount of mixture);

T - regulates the throughput of the carburetor diffuser by changing the position of the throttle valve.

First of all, screw L is adjusted, the standard setting is 2 - 2.5 turns from the twisted state with the engine turned off, screw H is set to the same position. After the standard settings are set, the saw must be started and allowed to run for 2 - 3 minutes, the engine will warm up and the carburetor will be ready for adjustment.

Important! Correct carburetor adjustment is only possible if a clean air filter is installed on the saw.

After starting, turn the speed screw to find the maximum engine speed at idle. Next, the screw is loosened counterclockwise a quarter turn. Precise adjustment of screw H is only possible with the help of a special tachometer; if it is not available, then the adjustment is carried out by ear. A correctly adjusted saw should work monotonously at maximum speed and maintain a stable speed. The engine should not run too fast.

Advice. If you have not previously had experience adjusting the carburetor of a Goodluck chainsaw or other similar ones, then it is better to contact a service center, since incorrect adjustment can have serious consequences, including the need to replace the CPG.

In conclusion of the article, we suggest that you read the reviews of real owners of Goodluck 5200 and Goodluck 4500.

Model GL4500M

A modern chainsaw intended only for private use, this chainsaw will not work for a long time in difficult conditions, because it has a limited resource and safety margin. Suitable for annual firewood collection and various site maintenance tasks. It is not recommended to use the Goodluck 4500 chainsaw in construction, as it is quite bulky and heavy compared to analogues.

Appearance and quality of parts

Externally, the chainsaw looks decent, plastic body, aluminum handle, convenient controls, but at first glance it is noticeable that cheap materials were used as much as possible in production.

After the first days of use, the quality of the materials reminds itself, scratches appear on the body, because the plastic is not shock-resistant, the handle bends, the shock absorbers break. It is especially unpleasant when the saw accidentally falls. The consequence of a fall is often the breaking of the chain brake control lever, since it is made of fragile plastic. This breakdown is the most common reason why owners of the Goodluck GL4500M chainsaw contact a service center.

Important! If you still choose the Goodluck 4500 chainsaw, then try to protect it from falls, because the plastic from which the body is made is too fragile.

If you do not take into account the quality of the body parts, then overall the saw is normal. It starts easily, picks up speed, and has the ability to regulate the oil supply for chain lubrication and the quality of the fuel mixture.

It is also important that it is easy to find spare parts for this chainsaw, and if you have some experience and tools, you can carry out repairs yourself, but let’s not deviate from the topic and return to specifics.

Technical specifications

The maximum power achieved at 9000 rpm is 2 kW. The saw is powerful and resourceful, which indicates high productivity. The engine is 45 cm3, not the largest volume, but it is quite enough. The Goodluck 4500 can be equipped with a saw set with a maximum length of 50 cm.

For a household chainsaw, a tire longer than 40 cm is not required, since this length is sufficient to perform all necessary tasks. Installing a longer tire and chain will add financial costs to operation, since a 50 cm tire costs more than a 40 cm one. Everything is the same with chains.

Fuel consumption depends on specific operating conditions and carburetor settings; based on operating experience, we can say that on a full tank the saw runs for about 30 minutes, during which time you can cut 0.5 cubic meters of wood with logs.

Chainsaw Goodluck Carburetor Adjustment

Why and how to adjust a chainsaw carburetor

A gasoline engine works by burning a previously prepared mixture of air, oil and gasoline. Adjusting the chainsaw carburetor is necessary to prepare the mixture in the required proportion. The operation of the carburetor determines whether the engine will work with the declared power or stall.

The principle of operation of the carburetor

Regardless of the manufacturer, the principle and operating procedure of the carburetor of internal combustion engines is similar. For mixing air and fuel, the carburetor is a device that includes:

air tube with constriction;
fuel supply system ;
adjustable air damper.

Air under atmospheric pressure, having passed the air cleaner, is supplied to the narrowing zone, where its flow is regulated by a flat damper blocking the cross-section. After the narrowing, a vacuum occurs in the pipe. As a result, the vacuum sucks fuel from the fuel supply tube, the outlet of which is regulated by a fuel needle connected to the float chamber by a nozzle. The design of a chainsaw carburetor is, in principle, no different from other fuel mixers for internal combustion engines.

The principle of mixing is to regulate the air damper and float level, depending on the degree of vacuum. We open the air - more fuel comes in, the engine increases speed. The correct fuel mixture ratio depends on the precise adjustment of the chainsaw carburetor. If there is a lot of air in the fuel, power drops and the mixture is called lean. With a lack of air, there is a high fuel consumption, incomplete combustion, carbon deposits on the cylinder and the exhaust of unburned fuel. This indicates that the mixture is oversaturated.

According to the instructions, the Ural chainsaw requires running-in using an enriched fuel mixture. Therefore, the carburetor comes from the factory with the setting for the break-in period. When switching to operating mode, the node is configured again.

Signs of a good chainsaw carburetor :

the engine runs smoothly, resembling a four-stroke sound;
fast acceleration;
At idle the chain does not turn.

When is carburetor adjustment required?

The new chainsaw is adjusted to the recommended mixture. All you need is fine tuning using three screws; there is no need to disassemble the carburetor. Purpose of adjusting screws:

without removal.

“L” regulates fuel supply at low speeds;
“H” is needed to regulate the maximum fuel supply ;
"T" idle air control.

Since the saw carburetor is adjusted by ear while the engine is running, safety precautions must be observed. The saw must be positioned stable with the cutters pointed in a direction that is safe for those present.

Before starting manipulations, it is necessary to mark the initial position of the screws with paint or a felt-tip pen. The exact settings for the chainsaw carburetor for each model are in the operating instructions.

However, more often it is necessary to adjust the carburetor after eliminating a malfunction of the tool. The reasons may be:

violation of the protective cap and unbalancing of the screws;
wear of the engine piston, requiring a different mixture composition for operation;
unsatisfactory performance of the carburetor itself.

How to adjust the carburetor on a specific model of chainsaw? Perform the operations sequentially, following the instructions. Here is the algorithm, the general sequence of actions.

There are two stages of setup:

basic, with the engine off;
thin - on a warm engine, idling.

The basic setting is carried out only for the fuel screws at low and high speeds. Smoothly and slowly, close the dampers completely until they stop. Also smoothly open both screws counterclockwise 1.5 turns. After this, start the engine and warm it up for 10 minutes.

How to adjust the carburetor on a chainsaw with the engine running:

adjust the idle speed with screw “T” by rotating counterclockwise until the engine runs stable at idle speed;
check the speed of the speed increase; when spinning slowly, turn screw L an additional 1/8 turn;
Set the highest rotation speed using screw H on the tachometer;
Check the carburetor operation at idle once and for all.

How to find a carburetor malfunction

However, adjustment may be preceded by repair of the carburetor itself when it cannot fulfill its function as a fuel mixer.

If fuel does not enter the engine for some reason, you need to check the condition of the fuel supply unit. Often the cause is the supply of low-quality gasoline, as a result of which the fuel passages become clogged.

If the fuel mixture has stood for a long time, the additives have broken down, and the mixture may clog the passages and grate with sediment. In this case, a long rinsing is required, which is done using solvents in a service workshop.

Comparative characteristics of popular chainsaw equipment of this brand

The high reliability and durability of Goodluck chainsaws can be confirmed by the reviews and wishes of numerous users from different regions of the country. Based on these models, several versions have been developed that fully meet consumer needs.

Strength test: testing equipment

Before praising yourself for setting up the tool correctly, check the unit for functionality. It should work normally: without interruptions, loud sounds, or caustic exhaust.

The following factors indicate adequate operation of the device:

the saw chain does not shake during operation and does not try to leave its “rightful place”;
the motor clearly responds to switching;
The speed gain is gradual and uninterrupted.

With a working carburetor, the chainsaw works smoothly and clearly, without failures, the chain does not fly off, the hum is clear and uniform

Is there something wrong? Try adjusting the bolts again. If even after this the saw does not cope with the task, then the problem is not in the carburetor itself.

How to set up a saw made in China?

The design of the carburetor on Chinese chainsaws is no fundamentally different.
The order and principle of setting also have no differences and are performed in the same order. The only difficulty that may arise during the work is determining the purpose of the adjusting screws. Typically the T screw is at the top and the H and L screws are located at the bottom of the carburetor body. There may be one more, additional screw. Figure 3 – Location of adjustment mechanisms

Usually their purpose is determined experimentally, slightly changing the position and monitoring the result. Once the purpose of the elements is clearly defined, further configuration is not difficult and is carried out in the usual manner.

Adjusting the carburetor of a chainsaw is an important and necessary procedure that must be performed periodically to restore the normal operation of the tool. This process does not create any fundamental complexity, but requires the user to be careful, attentive, and follow safety rules. The chainsaw chain is usually not removed, since you will need to observe its position

Therefore, it is important to constantly remember the possibility of its launch and exercise the necessary caution

The adjustment should be made smoothly, with small changes in the position of the screws, so as not to cause too sudden changes in the mode of rotation of the shaft. The result depends on the care and diligence of the user, and a properly configured carburetor will extend the life of the tool.
