HELP!! with my 75 Dart

Sorry to hear of the issues. BTW, you don't necessarily need a certified mechanic... I know a few who can't tune a carb to save their lives. You need a 'competent' mechanic for older engines.

Is it running rough at idle, or when accelerating, or all the time? Can you describe this a bit more?

In what way did you look at the distributor? The term 'looks fine' is a bit vague. Would you want a couple of tests that you could easily do yourself?
It starts up..runs but wants to die when i put it in gear after it's warmed up.. Like its on choke still.. It's sluggish to get up to speed but then seems to go fine.. It was back firing.. Seems like the timing May be off. I took the cap off..there's no visual cracks..minute pitting.. It's getting plenty of fuel. Any advice would be greatly appreciated! As i was saying..this all started after the accident. I can tell they messed with the Distributer because there's a Mark where it clearly had been sitting before.
