Premixing???? WHAT no one told me anything about having to premix. As far as timing I never touched it so I hope it was right also.

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.

Unhappy

OK, so now after reading that I guess I am looking for a GSL-SE block if anyone knows where to go to get one.

Please let me know and this time I will make sure to add oil to the fuel.

I am looking in my area on Craiglist but found nothing so far.

I really want to thank you for all your help.
