I need to remove the flywheel and stator on a GY6-150 engine, and the nut seems very tight. I haven't done one of these in a few years, and can't remember whether the threads on the crankshaft end are standard right-hand thread, or left-handed. Can anyone give me a quick confirmation of the thread direction before I maybe put a lot of pressure on it in the wrong direction? Also, in your experience, do the manufacturers typically use a thread locking compound on these nuts?
Thanks!

Righty tighty lefty loosey on the flywheel 17mm nut as Scooter pointed out. But your flywheel puller is reverse thread into the flywheel well. Yes, they use the bizarro Chinese white loctite and sometimes heat is needed to get the nut off the first time. I just use a barbeque lighter, one of those long jobs and it seems to do OK. A small butane torch works good too. The idea is to expand the nut but not the shaft so don't heat it up too long. An impact is pretty much a required tool.
