Ok I finally went out and got a blaster I can officially call my own. I got it for 100 from a friend who just wanted it gone. Apparently he bought it not running and put a working bottom end on it and tried to rebuild the top end himself. He said there was scared and tried to hone it out but might still have small scratches. He put a new piston in and said he had it running for 5 minutes and then the next time he tried to start it it wouldn't start. Now I have it. I did a compression test and after about 20 kicks it made its way to 85 psi so I'm guessing he didn't do the top end right and it probably needs a small bore to get the scaring out. But I don't know how you go about a bore. Do you take it to a machine shop and just say hey I want it this size or do I need to take them an oversized piston and say make this fit?
