My 71 Custom XL with an HH100 points engine quit today. I just got it back together recently. I checked for spark and none. I had put new points and condenser in it but decided to pull the cover off any way and look at points. The points were stuck open cause the push rod wasn't going back in. I pushed it back in and spun the engine and they opened again but the rod didn't go back in. I tried to get the rod out and it was brittle and broke off flush. Now I guess I have to take the side cover off to get to it right ? Also, where can I get a new breaker push rod ?
