Re: Hard to start with a backfire out the carb.
1) Timing is everything. Set your base timing first, then mechanical and vacuum advance. Don't trust the timing tab, check TDC with a piston stop.
2) Check your plug wires, cap, rotor, etc., replace as neccessary.
3) Carb adjustment. I like to start by finding a manual and setting them to base settings, then following the procedures. A $15 vacuum guage will work miracles. Q jets are pretty easy to rebuild if you have to.
