So here's my setup. I have a 413, that is pretty much stock I believe, with an electronic dizzy, MSD 6AL , Edelbrock intake and Holley 600 carb. It had a FiTech throttle body but the pump was going out so I'm switching it back to a carb. I bought the carb used and the pervious owner said he only ran it twice on his vehicle before removing it.
I have been adjusting this and that, reading, checking this and that, and reading some more. I have it to the point where it idles ok at about 700 rpm once warmed up. It does have a slight stumble upon take off and I can't get it to stop dieseling when I shut it off. The secondaries and primaries are fully closed too. I haven't had to adjust the primaries for idle purposes...yet. The floats have been adjust to where gas just barely trickles out when I rock the car while it's running. I have the timing set at about 8-9 degrees advanced at idle with the vacuum advance hooked to the port on the carb. This setup makes the motor ping pretty good under load. If I leave the vacuum advance off it doesn't ping but feels a little sluggish. Could just be me. What am I missing?? Should I set the timing at zero degrees at idle with the advance hooked up? What about the dieseling? I can't seem to get this thing to stop pinging and running on. Mind you it didn't do any of this with the throttle body.
