Hello everyone looking for a little help with an early model 064 that I recently rebuilt. It went fairly well for it being my first major rebuild, however when I got the saw the nut that held the flywheel on was stripped, I replaced the nut but there had been damage to the flywheel's keyway which I didnt notice until I was having trouble starting it and it would not run at full throttle, I think the flywheel was shifting around on the crank and my question is whether or not that would cause these symptoms? Also my flywheel is part #1122 400 1206 which is listed as an arctic flywheel but the saw has no generator or heated handles, this seemed a little strange, but can I just use the 1201 flywheel as a replacement and if so how hard is it to find? Thanks
