What causes a chainsaw to have too much compression?
Many problems with compression are related to fuel. Old or bad fuel can cause lots of headaches with yard equipment. Try draining any of the gasoline mixture left in the gas tank and add fresh fuel. If this does not solve the problem, it may be related to excessive fuel caused by problems in the gas lines and filters.
What causes a chainsaw to vapor lock?
Vapor lock occurs when the fuel (usually gasoline) within the fuel delivery system overheats and vaporizes too rapidly. The resulting excess gas bubbles accumulate to the point of actually blocking normal fuel delivery.
Will a chainsaw run with low compression?
Most chainsaws will operate well with compression readings that range from 100 to 160 psi. After checking the function of the starter assembly, the operator can move on to determining if compression is dropping or increasing.
How do I know if my chainsaw spark plug is bad?
If it’s not producing any sparks at all, your chainsaw needs a new plug. If there are only a few sparks coming out of one side of the electrodes but none on the other side, it’s not bad enough for you to worry about, but it will affect your performance.
How do you get rid of vapor lock?
Once the fuel system has cooled, you can help eliminate any vapor left in the fuel system by first pressing the accelerator pedal slightly (do not press it to the floor) while cranking the engine. Once the engine starts, hold the accelerator pedal down until the vehicle runs smoothly, indicating the vapor lock is gone.
Why does my chainsaw bog down when I give it gas?
If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.

What is the compression ratio for a chainsaw?
The compression ratio in a chainsaw is supposed to be 7:1, but the rings are bad and there is a 15% compression loss. What is the psi in the cylinder? The compression in a diesel engine is 17:1.
Can you clean a spark plug with wd40?
WD-40 removes carbon residue and keeps moisture away from spark plugs and spark plug wires. WD stands for Water Displacement, so if your spark plugs are wet or you need to drive moisture away from ignition distributors, for example, WD-40 is a product you should have handy!
