I did that...I'll go over it again tho. It makes me mad because it was supposably blown up...but here the piston ring was just stuck in the piston, so i got it unstuck and it had compression and ran but then it made a clunk'n noise in the motor. I thought the whole bottom end was shot, but here the key way was busted and the fly wheel was just lose. I put it back together and it ran good, but vibrated so bad. It's like i keep making out good by fixing it, but everytime i fix it, theres another problem. I'm trying to get this thing good for just the $550 that i paid for it. I'm trying not too stick too much money into it. I was hoping just to buy all new gaskets for the motor then sell it.
