One of the most common problems that chainsaw users often face is when their chainsaw seizes. A seized chainsaw should be quite the problem for chainsaw users, especially when they are in the middle of an actual job. A chainsaw can seize up when the carburetor was set too lean or whenever it isn’t functioning properly.
Look the chain saw over, and clean any debris or stuck pieces of wood from all areas surrounding the chain. Grab the chain, and ensure that it turns on the chain saw bar. If after freeing up the pull-cord or replacing it, you find it operational, this also means the piston is moving freely inside the chain saw engine.
If the pistons of your engine are jammed in their cylinders or the crankshaft is bent, it’s a sign of engine seizure and as a result, your chainsaw would be locked up. If no compression is recorded at the gauge, then most probably your engine is seized and you should consider investing in a new chainsaw. The sudden throttling up of your engine can raise the temperatures abruptly which can damage the gaskets and rings of your engine.
Fuel especially pump fuel doesn’t last long, looses it’s volatility and ethonal fuel absorbs moisture. I’ve never had saw issues using fuel a few months old or even 6 months old although I try to keep the fuel less than a month, same saw for thirty years. Hill Top no worries about the oil settling out of mixed fuel.

How do you know if your chainsaw sprocket is worn out?
The chain sprocket must be replaced if the depth of the wear marks reaches about 0.5mm, i.e. the wear limit. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it’s important to keep an eye on.
