Just wondering if anybody here has any clue how to troubleshoot and tune holley carbs? I have a 1985 ford f150 xlt lariat extended cab. Its got a ford 6.6L 400ci with a holley 0-7448 2bbl carb. So far as I can see its fast idle cam is stripped. As it turnes out the truck does'nt run too well without it..Anyways its like another member said if you dont post your problems nobody else on here learns. I'll let you all know if the replacement cam works or not. It should be here wednsday or thursday. (Auto value, ect, ect wont stock an item that small)
