Holley 1850 on a 302.
Runs pretty good, just rebuilt it and had to do alotta work and parts swapping to get everything going with it.

Few ???'s as I'm new to carbs:
Idle screws do nothing.... I set the floats correctly, transfer slot has less then 20thou showing. What else could cause it?
and it idles like a drag car (which I don't mind, but it seems odd).
Exhaust is kinda smokey

I *would* say the engine was wornout, but with the old 2v intake and 2150 it ran pretty smooth.


any ideas are appreciated.
