Chainsaw Repair

Great thanks. If I was to use airplane fuel because of the higher octane should I richen the fuel oil mix?

Rather than give you a direct answer, I'll try to give you pointers to better chainsaw running no matter what changed.

I prefer to adjust the chainsaw close to the two cycle / four cycle change over point. This has always been the mixture point of choice.

You will find that this point moves around with the heat built up in the chainsaw. What I notice is a chainsaw mixture going leaner in a big buried cut before the bar is through the wood. So I prefer to adjust the mixture to the weather and the job.

A chainsaw adjusted correctly for whacking limbs will get too lean in a big long cut in a tree trunk.

Likewise a chainsaw set correctly for heavy duty cutting will be too "fat" when starting the saw and cutting off one small limb.

A chainsaw adjusted correctly for the job and temperature in very hot weather will be too lean in extremely cold weather.

Likewise a chainsaw adjusted correctly for very cold weather will be too rich for very hot weather.

Moral .  . .

Learn to identify the change over point of the 2 cycle - 4 cycle  running of the chainsaw and keep your mixture adjusted for the chainsaw to run at that point in the job being performed.

Oh my?
Listen for the roughness-smoothness transition while leaning out from a too rich condition
