Where to start? 1. Engine is backfiring from tailpipe and carb (new carb). 2. Seems to overheat. 3. Idles rough. I've changed the points,plugs,carb. I tried to set up the timing. How do I set it up? I tried to look through the hole below the starter. I cant see any mark. Even if there was one, what do I align it too? Threre isn't any mark or pointer near the hole. Whats the pointer (o to 10) below the distributer for? what should it be set too? It's set to 10. The car is my Uncle's but I'm trying to help. Anyone know a good Packard mechanic in Sacramento ,Ca area? Thanks for the help in advance, Raul
