I overheated this motor (ran the tank too low), but when I took it apart I didn't find any damage. I went ahead and installed new pistons, rings, wrist pin bearings, o-rings, and base gasket. When I started it up, the rpms surged and the motor instantly got hot. It never even idled before, now it won't let revs down. I know it's gonna get a little hot due to the new rings, but not this hot. I ran 1/4 throttle through 3rd gear for 1 to 2 minutes, then it dieseled when I tried to shut it off. I re-torqued the head and cylinders, and didn't run it again.

When I tried to purge it, it got hot and the rpms surged still. It got so hot that I didn't even get it purged all the way. WTF is going on here?

EDIT: This is a 14 mil Cheetah on alky.

That was the next thing I was gonna do. Alky is funny. You have a clogged pilot on gas and it won't start...I guess if you block the pilot on alky..it still pulls enough from the main and pj just to keep the motor running, albeit lean.

Thanks..that was the answer I was needing. If it still does this after cleaning the carbs, I'll let you know.
