someone please help me...I kinda seized my motor a few months ago and decided to actually rebuild it I bored the cylinder .20 over put a new wiseco piston in it got new valve seals and put it all back together and I cant even pull it over more to get it to start..I got it to start once but it is the hardest thing to do. what should i do?

 

sounds like you need to fix the compression release.I have the same thing and do not have this problem.
