Not Ranked
New distributor in place, no change. However, I think I now know how to fix my running problem.. . .
I put together what 3 folks told me:
1) Try 1.5 turns on the idle mixture rather than my one turn I currently have
2) My local mechanic tried 7/8 turn and it was a little better, but lean idle
3) AED said that if I have it out only ½ turn or so, I need bigger idle air bleeds, like 6 counts bigger
1.5 turns made it worse, so I tried 0.5 turn. And it ran waaayyyy better. Then I backed off another ¼ turn and it stalled. Then I went 1/2 turn minus 1/8 turn and cruised for a long while. Runs awesome from 1800-2500+ rpm. The cruise is near perfect. The chug is 99% gone. Off the line is not for the weak at heart, it’s so lean (18-20) it’s hard to get moving, but then it dives to 11.8-12.5.
That tells me that that is where my problem is. The transition. I will try to get 74 sized ait bleeds to replace my carb's 68, to follow what AED told me and readjust the idle mixture and see where it goes. If this does not fix it, I may sell this carb and buy the 4150 street version (with less aggressive fuel curve) or a Demon, or Quick Fuel or an AED custom built carb. I may even drop to an 830-850 rather then the 950…. That's where we are now.
