Just as a little bit of background... after a rebuild I've been trying to get the thing to start up for a while now. Had a little trouble with a leak in a fuel line, then the fuel distributor, then it was issues with it not firing. Got all that figured out but now my problem is when I was trying to start it up it back fired. It happened twice and scared the hell out of me both times. Here's my theory as to what I think it could be:

1. There is a lot of fuel in the engine from cranking it over when it wasn't firing and now that fuel is being burned off and causing the backfire.

or

2. My timing is off (in other words I've set it wrong).


So my question is should I keep trying to start it up and see if it's just excess fuel in the engine and hope it starts? If not what would you suggest.

Thanks for the help.
