This is for you guys running Super Six slants with a Carter BBD 2bbl. When warmed up to normal operating temperature, what is your idle speed set to in PARK and then what does it drop to when in gear?
I tried tuning the carb to 750 rpm in PARK, but once I put it in gear and turn on headlights, it drops down too low for my liking. I now have it set around 810-820 in PARK, and it drops to about 600 in gear. That allows it to have a decent idle at stop lights - not like it wants to die.
Next, what about fast idle rpm while on the high speed choke cam for warming up? In other words, about how many turns on the high speed screw did you go just after contacting the cam?
Finally, how many turns "out" (richer) do you have your idle mix screws? I started with 2-1/2, but the engine would barely stay running. I think I now have them out about 5-6 turns. I smells like it is too rich.
If it is running too rich, would that cause it to diesel. For now, don't consider it to be a timing issue.
As you can see, I'm still having to tweak this replacement carb to find a good combination of choke, choke pull off, high speed idle, curb idle, and air/fuel mix adjustments.
Just wondering,
Jerry
