This is a 1977 Dodge 360-3 engine with about 35,000 miles.
I normally run the fuel\air mixture screw adjustment all then way in and then back it out 2 1/2 turns to get a starting point. From there I try to get the best balance between smooth enginf and max vaccum.
But on this one I can run both all the way in and the engine continues to run(rough) and backing them out doens't seem to make any big difference.
Basically, these adjustments have very little effect and the engine won't smooth out. Is it time to ge a new carburator?
