Quick fuel air bleeds

Dartish said

What are you running for engine combo? Carbs worked good since new, out of the box it was 10x better then the edelbrock it replaced. Jetting seems real close. So far I've replaced the stock power valve with a 8.5. Made a huge difference. But I'm pulling 18" vacuum at 600 rpm. T slots are almost perfectly square. Just getting tired of the rich idle.

360 comp cam .454 lift. 19" vacuum I also put a 8.5PV in I haven't been messing with my carb lately but I am going to try one more adjustment to .020 on the IFR's. I went from burning your eyes rich to not much smell of gas now just trying to get it spot on. What i found with just changing the air bleeds was that i was still rich at idle and going lean every where else. The Idle circuit is more so T-slot, a/f screws, and IFR's . I also tried going from a 68main jet to a 66 but that caused me to run lean at 1/4 to 1/2 throttle so the 68 is going back in when i do the restrictions again. .020 IFR is hopefully the last time I have to change it.
