FE Technical Forum / I have a carb question for the Gurus on 2X4 Holley setups. Idle stalls.
« on: May 24, 2022, 11:58:19 PM »
I had Drew do my 2X4 Holleys from Carl's. ( Repo BJ-BK) I went for a drive and out of the blue I had an issue with idle but runs fine about about 1600 rpm and up but wont idle at 900 as usual.
Because I have a Pertronix II I thought I may have a coil or module issue. I did the rudimentary testing and found no faults, including verifying sold ground at the distributor. Factory C5AF 427 Centrifugal advance unit.
The voltage is at 11.5 ( not loaded) and the coil is at .05 Ohm.
However, I pulled the carburetors off and noticed that the primary carburetor ( Front) has a rubber vacuum cap on the nipple on the metering block and it was compromised. Would that cause idle issues in itself? I am unfamiliar with that port and the OE BJ-BK units do not have them.
Any guidance would be helpful!
