The only question is which model to prefer. It is important to pay attention to whether you will use the tool often, as well as with what intensity. For periodic work, a household chainsaw is suitable, while for the construction of a wooden bathhouse or log house, you can consider a semi-professional or even professional model. If you cannot make a choice, then as an example you should consider the Partner P340S chainsaw, which belongs to the household class of equipment. It will be discussed below.

Chainsaw carburetor repair Partner 340
A frequent malfunction of the carburetor of the Partner 340 chainsaw is associated with a fuel leak (loss of tightness). First you need to check the integrity of the gasket between the carburetor and the engine crankcase. If everything is fine with it, then the problem is the carburetor is tight.
To check the tightness you will need a pressure gauge. The inlet of the measuring device is placed on the fuel supply hose. Then, using a bulb, a certain amount of air is pumped into the carburetor. The device readings must be at least 0.4 bar. After some time, the pressure is measured again. If it falls, the carburetor needs repair. This may be due to the following reasons:
- malfunction of the control membrane (in the main chamber) or the fuel pump membrane. The tightness here is broken due to the loss of the shape of the membranes or the appearance of holes in them. This problem occurs due to prolonged operation or overheating of the carburetor;
- the needle does not completely close the valve, because Low-quality fuel contributes to its clogging. In addition, over time, the geometry of the needle cone changes due to wear. Let’s also add here the insufficient mobility of the needle valve lever on its axis when it is worn out or bent. And its spring lost its elasticity.
- the plane of the petal valves in the fuel pump is disrupted. As a result, they are poorly pressed against the supporting plane and, as a result, the seal of the carburetor is broken (the pump loses performance).
A membrane chamber cover is installed on the side of the carburetor of the Partner 340 chainsaw. Through the hole in it, dirt gets inside the carburetor. When it accumulates, the membrane rises and presses on the needle valve lever. As a result, the lever does not completely close the fuel channel, which leads to over-enrichment of the mixture.
It is necessary to remove and clean this cover from accumulated dirt more often. Fortunately, its design allows this to be done easily and quickly (you need to unscrew the four screws on the side of the carburetor).
All of the above malfunctions, as a rule, have 2 main causes: engine overheating (lean mixture) and carburetor clogging (insufficient fuel cleaning). Both problems can be solved by correct adjustment and timely cleaning of the carburetor and air filter. Don’t forget about a high-quality gasoline filter element.
When cleaning, special attention should be paid to the mesh; the slightest clogging of it leads to unstable operation of the chainsaw.
Failed parts can be replaced by purchasing the appropriate repair kit.

Owner reviews
Andrey:
It so happened that I bought two saws - this one for the dacha and a little earlier, the HUTER BS40 for the village. I will compare them.
Build quality, materials - PARTNER is definitely better. HUTER is all sort of loose, one of the suspension springs touches the body during operation and rubs it. PARTNER in your hands gives the feeling of a high-quality tool, it starts very easily, the starter handle is comfortable. HUTER, unfortunately, has problems starting, and I rubbed a callus on the handle this evening.
You can feel the good assembly and materials of the case. Very easy to start. Light weight and comfortable ergonomics. Gasoline and oil consumption is low.
Things to Remember to Prevent Rebound
Tool kickback can occur when the front or end of the saw unit contacts an object. In some cases, a rebound can occur not only upward, but also to the side. If the saw chain becomes pinched along the bottom of the guide bar, the machine may pull the saw forward. If the chain is pinched along the top of the guide bar, the equipment may bounce back. In this case, the danger is especially high, because the operator is there.
In any of these situations, the technician may lose control of the saw. After reading the operating instructions for the Partner P340S chainsaw, you will have an idea about kickback. In this case, you can minimize the surprise factor. When the engine is running, the saw must be held with both hands. This will immediately reduce the risk of kickback and help maintain control of the tool. There must be no obstacles in the work area. It is important to avoid contact at the front of the machine with obstacles such as branches and logs that you may hit during operation.

Expert advice
Partner P340S 14 is equipment whose engine should not be started without preparing the tool. For a new chainsaw, you need to adjust the chain, pour the fuel mixture into the tank and oil into the oil reservoir. Protective gloves should be worn when handling the chain. In order for oil to flow to the chain and bar, the original design of the bar must be used. The chain brake lever must be pulled back.
The bar lock nut must be unscrewed to install the guide bar. The chain brake cover is removed and must be pulled outwards. The two plastic washers are discarded. They are used only for the initial transportation of the instrument.
Do-it-yourself adjustment of the Partner 340 chainsaw carburetor
Initially, the carburetor on the Partner 340 chainsaw was adjusted by the manufacturer to operate in maximum power and efficiency mode. Additional adjustment may be necessary if traction characteristics deteriorate, which is possible due to sudden changes in air temperature or when filling the tank with other fuel.
Before adjusting, it is necessary to clean the chainsaw carburetor from dust and dirt (it is better to use a compressor with an air nozzle for these purposes).
The carburetor adjustment algorithm itself is performed as follows:
- To access the quality (marked H) and quantity (L) screws, the chainsaw has special holes on the left side. For convenience, you need to remove the protective cover.
- Tighten both screws all the way, and then unscrew each 1/5 turn.
- We start the chainsaw and warm up the engine for 5-10 minutes.
- Adjusting idle speed. To do this, tighten the screw T counterclockwise until the engine starts to operate as stably as possible. At the same time, make sure that the chain does not rotate (if it rotates, smoothly tighten the screw until it stops). If the engine stalls at idle, screw T needs to be unscrewed a little again.
- We adjust the engine power and mixture quality. Smoothly pressing the gas, we wait for the engine speed to increase to the maximum. According to the manufacturer, the maximum speed occurs at 11.5 thousand rpm (use a portable electronic tachometer for an accurate determination). If the speed does not increase, you need to turn screw L counterclockwise 1/8 of a turn. The maximum speed should not be allowed to exceed the recommended speed, because this can lead to ignition problems. In this case, turn screw H counterclockwise, thereby reducing the maximum speed
If you don’t have a tachometer at hand, you can determine if the carburetor is adjusted correctly visually. When the engine smokes heavily during operation (the mixture is rich), screw L must be tightened a little. When the engine warms up and picks up speed, screw H must be unscrewed counterclockwise by approximately ¼ turn.
Sometimes it happens that adjustment does not help. The engine does not develop speed or stalls. The cause may be a clogged filter or air intake. It is enough to clean and re-adjust the carburetor if necessary.
Cost of spare parts
No matter how high-quality the equipment is, it may need spare parts during operation. The Partner P340S chain can also be purchased for 611 rubles. But you can buy an oil pump for 600 rubles. The gasket under the heat insulator will cost the consumer 120 rubles, as will the cylinder gasket.
A spark plug costs only 100 rubles, but a manual starter costs 700 rubles. An air filter for Partner P340S, the operating instructions for which were presented above and is included in the kit, can be purchased for 150 rubles. The cylinder-piston group is quite expensive - 2200 rubles.
