Analysis of the data presented allows us to note 3 interesting features. Firstly, the Husqvarna 142 has enough power for a household chainsaw, less than the average power of professional saws of the same manufacturer by about 20%. Secondly, its cutting headset is standard for Husqvarna and, if necessary, replacement will not lead to a long search or waiting. Thirdly, the manufacturer focuses on undemanding gasoline quality, without specifying the minimum permissible octane number. Therefore, the conclusion at the first step of the review is as follows: the characteristics of the Husqvarna 142 chainsaw are suitable not only for working in the country, but also for semi-professional use.
Here in Husqvarna 142 is a classic minimum. They are represented by a switch that takes the On or Off position, a choke position lever that can be in one of three positions, and a combined throttle position control lever with a stopper. Only "suction" needs to be explained here. Between the fixed positions of the open and closed throttle, there is a third stable position, corresponding to the half open throttle of the chainsaw carburetor. It is used when starting a cold engine after several jerks with a closed choke starter. Husqvarna 142 has no primer. Primary fuel pumping is carried out using the starter handle. Well, the fewer nodes, the less breakdowns!
The Husqvarna 142 chainsaw has a fuel setting and chain tension adjustment. As with most chainsaws, the tension is carried out using the adjusting screw; termination criterion. the chain does not sag and, at the same time, easily walks along the bus. Carburetor adjustment is required when weather conditions and fuel quality change. Symptoms for which it is necessary are as follows: the chain rotates at idle speed, the chainsaw stalls when you press the gas, does not develop speed, and greatly slows down when cutting. If you need to tune your chainsaw, we recommend reading our article on how to adjust the Husqvarna carburetor, which describes in detail all the nuances of adjusting Husqvarna saws, and also read this
Husqvarna 142 in use
The fuel mixture was prepared by us on the basis of AI 92 gasoline and Husqvarna HP branded two-stroke oil in a ratio of 50 to 1. It is interesting to note here that in the absence of oil added in the indicated ratio at hand, the manufacturer permits the short-term use of high-quality oil diluted with gasoline in the ratio 33 to 1.
We operated Husqvarna 142 for about an hour. It fits perfectly as a household chainsaw: almost complete absence of vibrations in the hands, quite tolerable noise level and, most importantly, excellent cutting ability. Trunks of fresh pine and dry birch with a diameter of 26 cm were repeatedly sawn for an average of 7 seconds each. The dry oak gave in a little more slowly; it took about 14 seconds to cut a log with a diameter of 24 cm. Sawing speeds are slightly lower than those of the professional chainsaws that we tested, but these are also saws of a different order of magnitude. The Husqvarna 142 is not afraid of working at full power, high revs are even recommended by the instructions. The brake is perfect. the chain stops instantly.
Troubleshooting and DIY repair
Malfunctions are simple, if they do not require disassembling the chainsaw to eliminate them. For Husqvarna 142, the methods of finding them, as well as eliminating them, are no different: it all comes down to checking the condition of the spark plug, the fuel level in the tank, etc.
In the event of easy-to-fix malfunctions, individual units must be removed, replaced or repaired, and then assembled a Husqvarna 142 chainsaw. This is how the shock absorbers or carburetor are replaced and the starter is repaired.
If the chain is not lubricated, we recommend that you look in which the lubrication system, its disassembly and assembly is considered in detail.
In the event of complex faults, complete disassembly is required. The device of the Husqvarna 142 chainsaw is not complicated, but you must be sure that for a quality repair you can:
- Get device drawings with a description and detailing is within your power;
- Perform troubleshooting and reassembly.
Is it worth it to independently repair the piston group of the Husqvarna 142? For a high-quality overhaul, you must have at least accurate instruments. a micrometer and an internal gauge. which can cost you more than spare parts.

What is a carburetor?
A carburetor is a device that is designed to prepare a combustible mixture of liquid fuel and air, which ensures the operation of carburetor internal combustion engines.
Modern carburetors are equipped with many different devices and systems, which have numerous holes of different calibers, an extensive network of channels, pneumatic chambers and linkages.
The carburetor is one of the main parts of any fuel-powered equipment. To ensure the normal and stable operation of the equipment, it is necessary to periodically check and, if necessary, adjust the carburetor.
Chainsaw carburetors have three adjustment screws. Screw "L" is designed to regulate low speed, screw "H" is responsible for regulating high speed, and screw "T". for idling of the chainsaw. So, with screws "H" and "L" they regulate the ratio of the mixture of air and gasoline, when the screws are unscrewed, the revolutions increase, as the mixture enriches, and when tightened, the revolutions fall. Generator carburetors often have only one adjusting screw, but many other modifications of this part are also possible. Its adjustment allows you to eliminate excessive fuel consumption and leakage of unburned oil.
However, there are quite common cases when adjusting the carburetor cannot fix the malfunctioning of the equipment. This is due to the final breakdown of the part, which occurs as a result of natural wear and tear or due to improper operation.
