ok everyone i have gotten all the issues with the duster straight and now its running and going down the road. one question i would like to know is when i stay steady on the pedal it feels jerky doesnt go smooth but as soon as i give it more gas to accellerate it drives smooth. any opinions.

What carb do you have ? How fast are you going and in what gear , what's the engine RPM ?

If you are in to high a gear at too low an RPM for the speed you are going it will do exactly what it's doing ... say you are doing 20mph in 4th gear and the car has 2.76 gears ...

(1) go up 4 (pri jet sizes)& (re)try it (2) put em back where it was (3) disconnect/plug the vac adv & (re)try it (4) hook it back up. Holler back

I have a holley 600 double pumper and the car has 323 gears. it does it with every gear at any speed that im trying to cruise in so for example going about 20 in second gear very low rpm it does it. ill try to do some of the tuning some more and see if i get someone going good.
