Where are the idle mixture screws set? Most of the time if you leave them at 1 1/2 turns out, it's going to be rich.

Is fuel dripping in from the boosters?

The issue IS NOT anything related to the PCV or booster. Isolate the intake and solve the carb/timing issue and worry about the other stuff later.




The car has manual gearbox,are not 800 rpm are a bit high?
If i use the idle screw i loss the transfer slots adjustment.Don,t understand the Holley design,why that screw is so accessible.
The mixture idles are 1&1/2 or 1&1/4 (i don,t remember how i set them last time)turns out.
Tomorrow i will check if i see fuel dripping from the boosters.
Also it has manual brakes,the only thing connected to manifold are the headlights covers.The vacuum advance does not work so i have plugged the port.

Thanks
