383 with 4 bbl initial fuel mixture setting

[scottveazie]

Being a reformed small block chevy owner, I've yet to tune a mopar 4bbl on a 383. Going by what I've done it the past, first you set the timing, disconnect vacuum advance and block off, and turn in each screw one at a time until the engine stumbles, and then turn back out how many turns? I did a quick and dirty on my 383 by turning them in until it stumbled, then back out a full turn. Should I turn them out further? I do not yet own a vacuum gauge. Am I remembering things correctly?

I've always backed them out until it smoothes out and called it good.

I set them with a vacuum gage to get the highest reading.

The right way:

The way everybody really does it:

I've always backed them out until it smoothes out and called it good.

Vacuum dial here, although I admit I used to do it with the needles also. I like the vacuum dial better, more precise....if you know how much vacuum you should be pulling there's no guess work as with adjusting needles and idle and rpm and blah, blah

" first you set the timing, disconnect vacuum advance and block off, "
Technically you're supposed to set the timing with the vacuum advance blocked off. If you set the timing with the advance hooked up you'll be retarded, and nobody wants a retarded car. You're reformed.
