I have a 360/380hp crate with a 4spd coldest plugs I can find idle set at 750 timing 32 and 180 stat. It also has a Pertronic in the distributor. It diesels at every shut down when warm.
Well pulled the car out haven’t touched it in 6 months. Still diesels on shut dow. Holley hp 750 dbl pumper. Yes it will run with mixture screws turned in. I have set the initial timing at 10*,14*,20*. Idles 750 rpm. I had issue with pvc so temp removed. Rear throttle blade shut. It pulls about 9 on vac at idle.
If it runs with the mixture screws turned in it's bleeding fuel over somewhere. Power valve blown? Floats set too high? Just thinking out loud here.Well pulled the car out haven’t touched it in 6 months. Still diesels on shut dow. Holley hp 750 dbl pumper. Yes it will run with mixture screws turned in.

Missed that, yeah he's running on the mains and not the idle circuit. That can cause issues..If it runs with the mixture screws turned in it's bleeding fuel over somewhere. Power valve blown? Floats set too high? Just thinking out loud here.

You will need to do some homework on the correct spark plug and get the proper ones back in. Too cold of a plug will make the engine run like crap and idle rough and rich. If the cam makes the engine idle rough and you can't get it slow enough, you may need a higher stall torque converter. There are many unanswered questions here that need to get asked and answered to fix your problem.Thanks still playing with it.
