73 sportster engine question
Hi, Just bought a 73 Sportster that has been in storage for 15 years. The issue I have is the rear intake valve was just kissing the piston and not letting me turn it over. Took the heads off and could see that it was hitting. Also pulled the side cover off to see if cams were timed correctly, but they fell out so could not tell. Motor now rotates nicely and cylinders are good.
So the question is, what are the reasons that come to mind as to why it was hitting. Valves are not stuck. rockers are good as well, Thanks in advance for your answers.

piston in backwards
Hi, Besides the cam being out of sync, the rear piston was also installed with the notch facing the exhaust valve. I am slowly learning the details of the motor by trial and error.
