HELP!! with my 75 Dart

If you are talking about the air/fuel idle mixture needles, they can run without one of them a lot of times.
They will run like crap though.
I would be all over them for that ****.
For 300 bucks you would think they could find one.

Check or replace the distributor cap and see how it acts (but with the missing needle back in it):D
A hit like that can easily crack a cap.
They did actually replace it however it took 9 turns to snug it! Then i did the turn and one half back to factory..she does have an rv cam so the adjustment would be slightly more but not 9 turns! Do you or any one know of a certified mechanic or is anyone reading this certified and in my area (Bellingham wa) who would be willing to take a look at her?
