HELP!! with my 75 Dart

Dam holleys...not my favorite. But i can almost guarantee there are a dozen videos on how to rebuild/repair/adjust...
Oh...believe me..I've watched several.. Technically i don't feel i should have to do any of it because i can guarantee it was all as a result of the accident..and as i was saying..her insurance is claiming 100% at fault.. That makes me Leary of doing anything myself.. If i could find a knowledgeable mechanic to confirm my suspicions then they would pay for it.. Darn it!!!
