Doesn't matter anyway, because by the time you exchange it and pay shipping it costs the same as buying a con rod and piston and sleeve. SO no biggie, but if you didn't break it in right and you were going nuts and not usign after run oil or air filter oil I can see why it blew the engine, lol
I use after run oil (couple drops down the carb and cylinder-with piston at BDC) and filter oil for my air filter(filter always installed). Hmm..me going nuts and running my car full blast..I would never do that!
