It has a brand new rebuilt stock BBD carburetor, electric fan, aluminum radiator, aluminum valve cover, and power brake booster. I am unable to get the idle speed set correctly. If I adjust the two mixture screws on the carburetor to get the vehicle to idle lower, it will stall out when stopping or will not start. If I adjust them the other way it will not reach top speed. Right now the best it will run is when I have the idle set at 1100, which keeps it running on cold start and stopping, and allows it to reach top speed. What do I have to do to get the idle to where it should be in the 600 rpm range? Also, I cannot unscrew the curb idle screw out anymore as I have it out as far as I can get it. I also see that the there are some uncovered vacuum ports like the one on top of my air filter duct, and what looks like two ports near the manifold that are small and black and not capped or connected to anything. Looking forward to hearing any advice you can offer. I am also not worried about any emissions requirement because this vehicle does not need to get inspected in New Jersey.
have the same problem?
