So today 8/9/20
I opened up the mixture screws a full turn - rich and reset the idle at 900rpm That made the the stalling worse, barely made it home with the car. This pretty much proved to me that is getting to much fuel.
So I thought let's go back to the basics, for decades I have been setting idle screws to the highest idle rpm and then added 1/4 to 1/2 turn rich always seamed to work OK.
I went to Edelbrock's website and watched a video on tuning their AVS carb's.
They tell you to set the mixture screws for the highest idle rpm and the lean it 1/2 turn for "best lean idle". I said this cant right, lean it out?
So what the hell, give it try what do I have to lose at this point.
I set the mixture screws using Edelbrock's procedure and I'll dammed - no more stalling. You could have knocked me over with a feather.
I am still going to change out the fuel pump to bring the fuel pressure down to 6 psi at the carburetor.
Thanks to all who responded.
