This is where I get parts and rebuilds. Have you disassembled it yet?

Putting time and money into an older engine can be a gamble. I have decided to replace any two stroke that has age and time with a 4 stroke. The reason is the ethanol gas. It just seems to take out two strokes after a few hundred hours no matter what. The last few engines I had here worked well on egas at first, but lost compression and had starting problems after 6 months of use. When bore scoped the aluminum from the pistons was coming off on the cylinder walls. These are engines used by commercial guys so they are used a lot. Most are bought used off people that used them very little.
