How much compression should chainsaw have?
According to Stihl USA, the minimum compression reading for their chainsaws should be around 110 psi. Some individual engines may run a bit higher or lower and the temperature of the tool can affect readings. A cool chainsaw runs low, while a hot engine that’s been running for awhile will usually be higher.
Why does my chainsaw have so much compression?
High compression is usually first diagnosed when the starter rope refuses to pull. It is much more common for the starter rope to be causing some friction or for it to be sprung too tightly. Pull the rope out and oil it to see if that helps the problem.

How do you lean out a carb at idle?
The first thing to do is not set up the idle speed, but to set the Idle mixture screw to lean best idle setting. First, turn in the mixture screw until the engine dies or runs worse, then back out the screw (recommend turning ¼ to ½ turn at a time). The engine should pick up speed and begin to smooth out.
Why do loggers run upside down bars?
Every chainsaw bar has been designed to be mounted right-side up or upside down. The reason for this is that it allows the user to extend the life of his chainsaw bar by 50%. Flipping the bar will give the heavily-used areas some relief from wear and tear. This reduces a chainsaw’s ability to cut accurately.

What causes a 2 stroke to have low compression?
Worn piston rings can cause incomplete sealing, resulting in lower compression and more difficulty in starting. Worn piston rings or reed valves that are no longer sealing properly may be the cause of the poor startability characteristic.
How much compression should a small 2 stroke engine have?
Normal compression is between 90 and 110 psi. Conclusion: You can follow the steps in this article to quickly diagnose all your two-cycle lawn equipment.
How do you fix low compression?
A healthy engine should have 100 PSI per cylinder. If two cylinders next to each other both have low pressure, a blown head gasket is a likely culprit. If you discover you do have low compression, the only solution is to replace the leaking part whether it’s the piston, piston ring, camshaft, head gasket or valves.
