Owner reviews
Over 9 years of flawless operation, I replaced the starter and clutch spring once. The car is quite decent in terms of its capabilities. Among the disadvantages, one can note the high cost of branded oils. My saw uses chain oil twice as fast as gasoline. As far as I know, this phenomenon is typical for many budget cars. Test substitution of a new oil pump did not produce any results. I found a suitable equivalent, the TAD-17 transmission, and the situation stabilized. Other shortcomings include the lack of a toothed stop for securely fixing the saw when cutting round timber, the lack of visual control of the fuel and chain oil levels, and a not very convenient chain tightening scheme.

I liked the saw, it’s light, easy to use, quite powerful and easy to maintain. I have been using it for almost 7 years, the annual production is within 50-60 cubic meters of firewood. The tire is long enough to fell old trees. I bought an expensive carbide chain for sawing oak, but now I have big problems with sharpening. The engine is sensitive to fuel quality and sudden changes in air temperature. In some cases it is necessary to compensate by additional adjustment of the carburetor. At one time, I bought the instrument for only 8,000 rubles. Now I regret that I didn’t buy two at once. The service said that the production of cheap chainsaws was transferred to China. If this is the case, we can expect that relocation will inevitably affect the quality of the product range. Dimon

Carburetor adjustment
A separate section covers the carburetor adjustment sequence. Correct tuning of the fuel system contributes to stable traction characteristics and economical fuel consumption.
The work is carried out provided that the air filter is completely cleaned and the power unit is warmed up to operating temperature. By rotating the screws, quantity and quality, the engine is brought to optimal operating mode with good throttle response and stable idle speed.
Additional adjustment may be required when switching to fuel with a different octane number, or when switching the tool to winter or summer operating modes.

- The air filter replacement period is every 50-100 hours;
- muffler cleaning - every 50 hours;
- carburetor adjustment - once every 100 hours (every six months);

Basic chainsaw malfunctions and how to fix them
Table 1. Malfunctions of the Husqvarna 142 chainsaw
| Malfunction | Possible reason | How to get rid of the problem? |
| 1. The chainsaw begins to stall during operation. | Low quality fuel, old fuel mixture. | Replace the mixture, after washing and drying the fuel tank, use good oil. |
| 2. The device vibrates strongly. | Make sure that the anti-vibration system is well secured and that all parts of the chainsaw are securely fastened. | Secure loose connections and check anti-vibration springs. |
How to set up a chainsaw
In the process of repairing Husqvarna chainsaws with their own hands, they identify some malfunctions that appeared as a result of incorrect ignition adjustments and carburetor settings.
The mechanism is responsible for engine speed and is adjusted for operation taking into account the necessary conditions:
- climate:
- height above sea level;
- petrol;
- loads;
- oil used.
By default, for productive work, the factory settings of the carburetor of the Husqvarna chainsaw are set during testing.
The device has 3 customizable areas:
- “L” - low speed jet;
- “X” - high speed jet;
- “T” - idle speed adjustment screw (XX).
The standard settings are:
- "X" = 11/4 turns;
- "L" = 11/4 turns.
To set up the chainsaw, after break-in, adjust the carburetor: first work with the “L” jet, then with the XX “T” and “X” screws. When “L” and “X” are rotated clockwise, the quality of the working air-fuel mixture deteriorates; when rotated counter-clockwise, it becomes richer. Rotating the screw “T” clockwise increases the idle speed.

Based on the reviews of the owners, the following disadvantages of the Husqvarna 142 chainsaw can be deduced:
- all chainsaws from this manufacturer work most efficiently with fresh fuel mixtures and good original oil; some models do not want to start with “counterfeit” oils;
- expensive components.
Where to look for the reason or where to start checking
All chainsaws have the same design and work on the same principle. The structure of a chainsaw can be found in this material. It doesn’t matter much what brand the instrument is - Shtil, Husqvarna, ECHO, Champion, Partner, Sturm and others. A malfunction that manifests itself in the form of a chainsaw stalling when you press the gas can occur equally on both expensive and high-quality tools and on budget Chinese devices. If a problem arises, it needs to be solved.
A chainsaw is a system of mechanisms consisting of parts. Any part in the mechanism can fail, which will lead to partial or complete failure of the tool. If the tool’s engine starts, this does not mean that the chainsaw is fully operational. When the engine stops working when the speed increases, there are corresponding reasons for this.
In case of this malfunction, you should first pay attention to a number of the following tool mechanisms:
- Gas tank - make sure there is fuel. If there is sufficient fuel, you should also check the serviceability of the fuel filter, the connection of the supply hose to the carburetor, and also make sure that the breather is working
- Spark plug - if everything is in order with the fuel supply system, then you should check the serviceability of the spark plug. By the color of the carbon deposits on the spark plug electrodes, you can determine the cause of the breakdown. If the carbon deposits are brown, then the spark plug, ignition and fuel supply system are operating in the correct mode. The presence of black carbon deposits indicates an ignition malfunction, and if the electrodes are wet, then the carburetor should be checked
- Muffler - over time, carbon deposits accumulate in the exhaust gas removal device, which helps reduce the throughput of the mechanism. If the exhaust gases have nowhere to go, they will interfere with the normal operation of the engine. In addition to a decrease in power, if the muffler is faulty, the engine will stop working when the speed increases
These are the main parts and mechanisms that should be checked first if a malfunction occurs when the chainsaw stalls when the accelerator is pressed. There are other reasons why a chainsaw engine stalls when the gas trigger is pressed. What else can contribute to the occurrence of this malfunction, as well as the specifics of troubleshooting, we will find out further.
