You are making me rethink this motor rebuild and going to a newer one instead.

The oil injection has been removed on that engine. Its common practice, especially in custom applications and when modifying/ changing carbs, etc. An arguably standard amount is 1 oz. per gallon of 2-stroke Tc-w3 added to the fuel. Your internal metal seals (apex, side, and corner seals) were not being lubricated (comparable to piston rings). Yo uprobably have quite a bit of internal wear and may be better off getting an entirely new motor. For simplicity sake I'd recommend staying with a GSL-SE block so you won't have any fitment issues.
