Stihl 441 M-tronic timing advance

[ccronin]

Has anyone filed the flywheel key on a 441c to advance timing? If so, what were the results? I have an extra flywheel and thought I might try it.

Yes absolutely it makes a difference.

You got all the digits, just in the wrong order .020 not .002

Wut are you just making a goofy offset key to make this work?

That would be nice but their keys are cast into the flywheel. Takes a steady hand to either get in there and whittle the key, or cut the key out.

I use a little file or a small burr
