Hard starting when cold

Just checked the timing again and put the trans in neutral and plugged the vacuum advance. It is still reading around 11 degrees BTDC.

Is it supposed to be retarded during break in or should it be at 0 as the factory spec calls for? Can this be part of the reason it is hard to start while cold or does it just sound like it's the carb?

Before the rebuild I used to have it advanced a little.



67Dart - When I start it, I floor it once all the way and hold it there while starting (what the owners manual says). Usually, I end up letting go and try it a few times if it doesn't start. Is that your 12 barrel setup??
