Husqvarna Saw Stalls At Idle

Candle problem

Checking the performance of the candle must begin with a visual inspection. The candle must be dry and clean. If the saw stalls, chances are the candle has been flooded. This happens with improper cold start attempts, especially with inexperienced saw owners. In this case, you need to try either installing a new candle, or drying the old one.

A carbonized candle can signal both the quality of the mixture and malfunctions in the operation of the carburetor: the reason is hidden either in the overflow of fuel or in the supply of oil to gasoline.

Another breakdown can be associated with the ignition unit: when there is no spark. As a rule, in this case, the candle itself remains clean, there is contact between it and the high-voltage wire. The ignition block is usually not repaired, but completely replaced.

Why the chainsaw stalls at idle

Malfunction of the cylinder-piston group

As a result of scuffing on the piston walls, the considered speed problem may arise. Seizures can usually be found on the muffler side. As a rule, this breakdown is solved by replacing the CPG, the cost of which can be comparable to the price of the saw itself.

Replacement of hoses, oil seals, gaskets is required

Any plastic and rubber elements deteriorate over time. If the saw works on XX, and when you try to increase the speed either does not gain them, or does it very weakly (well, or stalls), you need to check the hoses and seals for integrity. Hose problems are usually detected simply by inspection, but the loss of tightness of the seals can be found out in most cases only by supplying air under pressure.

A shim problem is usually found immediately or shortly after a saw is repaired. If you or someone has recently disassembled the unit, after which the described problems arose for no apparent reason, you need to check the quality and correct installation of the gaskets.

  • The carburetor is incorrectly set. This problem can be identified by how the device is started up on a cold one. If it is performed without closing the air damper, and the engine starts without a preliminary flash, this means that after heating the engine, the fuel fills the candle. The solution to this problem is to adjust the carburetor. Details on carburetor adjustment
  • Coil (ignition module) malfunction. You can identify this problem by sequentially checking the spark, first on a cold and then on a hot motor. If there is no spark on a hot engine, then the ignition coil must be replaced.
  • Defective spark plug. In this situation, as in the case of a malfunction of the ignition module, the spark disappears when the engine heats up. It is necessary to replace the spark plug with a new one, and if this does not lead to a solution to the problem, then the ignition module and the distance between it and the flywheel should be checked.

The chainsaw starts and stalls. the reason

If the chainsaw starts and stalls the first time you try to do the job, then the reason may be problems with the chain brake or its jamming due to lack of lubrication. In this case, the oil level is measured. If the amount of lubricant is sufficient, then the cause may be in the tube that leads it to the lubricating mechanism.

Another reason may be a broken carburetor. If he only needs adjustment, it can be done independently in accordance with the instructions. If the carburetor needs cleaning or repair, then you cannot do without the help of professionals.

Another possible cause of this malfunction is a low fuel level in the tank. In this case, the saw stalls when tilted, because the remaining fuel mixture ends up in the part of the tank opposite to the place where the suction tube is located.

Why does a chainsaw stall under load

Sometimes the saw will not function properly under load. This is most often caused by improper adjustment or leaking carburetor. In addition, air leaks through the carburetor gasket or crankshaft oil seals may be the cause of this problem. A tool that is unable to function under load also cannot maintain idle speed reliably.

Diagnostics begins with checking the carburetor and crankcase for leaks. If air leaks through the crankshaft oil seals, they must be replaced. If air leaks in the carburetor are detected, a repair kit of gaskets is required to solve the problem.

If these actions did not lead to the desired result and the crankcase of the engine with the carburetor is tight, then you need to adjust the carburetor.
