Idle fuel bleeds are too large.

Yes, idle feed restrictions could be a bit large. Did you plug the secondary P.V. and go up 5 or 6 numbers? How much base timing, and total?

Do you have a power valve in the carb or is it blocked off ?

richie 2 · 12-27-2020, 09:49 PM

950 holley HP. nice carb..... 3.5 pv, timing @ 18 inital/35 total. (pump gas)

You said 8 inches of vacuum at idle. Was the car in drive or in park when checked ? I always adjust the carb, idle mixture vacuum etc. in drive. Being in park raises the rpm and vacuum readings. Just checking because if overlooked it will not be an optimized setting of the carb. Good luck.
