Sounds like timing is out to me if rings were going you wouldn't have good compression. And poor rings won't cause it backfire.

Was your fly wheel off? Mine did the exact same thing. I had two engines apart at the same time, grabbed the wrong fly and put it on, fit great but I got the same effect that you are experiencing now. I swore at it for a few days until I realized what I did.

what should I be looking for when getting fly wheel off,as for wear,broken parts.or what do you replace?and if timing is out who,s best for spec,s getting answer from shop....well i guess helps not free....

Just check that the halfmoon key on the crank lines up with the slot on the flywheel. Having a major brain fart, can't remember his name. Martin West Edmonton. He has been there forever, when I remember his name, I will update the post.

Did you have any part of the motor apart when you had the motor out?

This might sound like a real stupid ? But just thought of it. Are your spark plug wires on the proper plug? easy enough to mix up and stupid enough problem to not think about it.
