Grab distributor and twist it clockwise... it needs more initial. If the engine picks up RPM when you do that THE ENGINE WANTS THE TIMING, PERIOD!

Put 16 on it at idle, turn the idle speed down to 850-900, reset mix screws to highest vacuum and see what it does. You'll have to change the mechanical. been through this before, read the other post you started. Don't drive it until you alter the mechanical advance.

IMO, Total timing method is a rotten method for timing a street driven car.

Only time I have a tune up on a car like what you currently have is if it needs to be smogged!

Positive you don't have vacuum leak issues?
