Ditching a quick fuel carb.

What is your INITIAL timing? I had the same problem with a quick fuel. With the cam I have I needed like 20 degrees of initial timing so I could back off the idle speed screw and actually run off of the idle circuit. You are probably super rich at idle because youre idling off of the primary a bit. I down jetted 2 sizes in the front. went up 3 sizes in the idle air bleeds. I also put a bit of a smaller power valve in the front. I suspected the power valve was dumping fuel into my idle mixture because I only had like 8.5in of vacuum and a 6.5 power valve. Just my experience. If I had to do it again I would have gone with a 650 instead of a 750 and possibly bought a blueprinted carb. Good luck!

Yeah I can't get it to just idle on it's own it wants to rev up, so I can't get an initial on it. I was leaning towards just getting another carb because it would probably cost just as much to take it in to a shop and have it looked at. As I don't know much about carbs. I did down jet this carb last year hoping to have got it closer but it looks like it did'nt work. I put the smallest jets for primary I think 67 or 68 and I think 70 or 72 secondaries and adjusted the floats and backed off the fuel pressure. I do have a 6.5 power valve in the carb right now. Last fall when the car was running initial was around 20 on my car as well. It would run real well but the plugs would'nt last that long before fouling.
