just got me a '67 Barracuda
My 63 ran about the same way, I adjusted the valves and it ran much better.
Just wash out your filler cap with gas then soap it down and rinse.
The #2 picture is a 66 / in my valiant, Not sure if they vented the 67 or not to the filler cap.
As you can see I changed out the point system to electronic.
Did you say you changed out to a new distributor? at low rpm's it could have to much wobble if its the old one.
