So i bought an 82 a couple weeks back, guy said it was running right before i bought it but couldn't get it started when i was there. Took it home, carbs looked clean, checked compression and was getting a whopping 0 in the LH cylinder, valve stuck open. Took the valve cover off and low and behold a busted camshaft (Pictures). My question is, has anybody dealt with this before? Is it an easy fix? What are the chances that i have shrapnel down in my valves and that those will also need to be replaced?
