The distributor cam should wear evenly (.010 is quite a bit of difference). The distributor shaft might have gotten bent by an overly aggressive rebuild. If it's bent you should see the wobble as it rotates. Even so, it should still fire and run if the points are opening and closing. Check across points with them closed and open with an ohmmeter. Any resistance across points when they are closed may prevent coil from charging and making sparks. I have had a recurring problem where my points keep getting covered with something. Never did figure out exactly what is going on. I've tried three different sets of points, polished like a mirror and the problem just comes back. My coil went bad at one point and I thought that might have been the problem all along. Nope, three weeks later had the same problem. Engine failed to fire, popped cap, polished points, checked gap, put rotor and cap back on, and it fired right up. The only theory I have left is this may have something to do with it being much wetter than normal for the last 2-3 years.
