I have been fooling with my carb for awhile and have not really gained much so I figure I would post some specs and see if anyone has any suggestions.
This is a mild built 304 with a mild cam (not sure any spec's info from PO) Eldabrock intake, factory exhaust manifolds and custom 2" dual exhaust.
I have a Holley 600CFM 1850-3 Carb which now has 64 Main Jets, #65 PV and a black vac secondary spring. Checked vacuum at 13". I have set the bowls so a trickle comes out of the sight plug when rocked. I have not touched the secondary as it is my understanding on this carb it is a plate?
My problem is I am running rich at idle and at speed. I can smell gas all the time. Checked plugs and thy are a little black around the outside and dark brown in the center. I went down from 66's to 64's on the mains based on what the Holley instructions recommend.
Any suggestions would be greatly appreciated
