Quick Fuel Slayer Rich!!!! installed LC-1 wide band

67dart273,
I did originally set it with a vacuum guage got my highest reading which did raise the idle. Thats when I set the idle down to 750rpm. Idle good but at a rich condition
I'm now at the point were I believe my mains are to big. Which using the AF guage in my opinion confirmed. Once I get the smaller jets, I will start from scratch again as you described.
