Just got a blaster on trade n guy gave me a top end n piston with it..put the top end on and it fired up for a few seconds then stopped ..crank it back up it had a pingin sound so i took top end back off inspected piston put top end back on then it wouldnt fire up seemed like it didnt have enough compression it read 60 psi..so i took top end off again and now the piston acts like it doesn't want to fit it goes in top end but its hard to go up n down now seems like it got to big but i didnt do anything different when taking top end off or drop piston..piston still looks new

Not sure of the exact name but piston ring locating pin will do. The ends of the ring go on the pin so they don't rotate , catching the ends in a port. I'm sure the manual has a better explanation for this. Either a Clymers or the PDF on here.

Did you make sure rings were located on the pin in piston ring groove?
Took rings off just to see if the were bent but they r not n put piston in upside down just to see...it used to fit fine
