I have no idea if cutting creosote material, itself, is relative to
the problem.

Any clues as to what needs to be done to get my saw back up and
running properly?** coming week.

I'd take the chain off and clean everything.* I'm wondering if the
creosote has it gummed up

Have you checked the spark screen? Its a screen that looks like the
muffler gasket when assembled. I've had 2 engines that ran properly
until warmed ( operated for about 30 minutes). Then they would start but
could not open the throttle. Removed the plate. Replaced the muffler.
Ran like new. In locales that have prominent big brother activity its
illegal to operate the engine w/o the screen.

What oilmix are you using, and what fuel?
