So i have been trying to get my buddies camaro runnin right, and i am thinking that we have a major carb issue. its a 4160 style i think, no metering plate on the secondaries, so i know its not a 4150. holley wasn't much help, they said i needed the carb size and type, but they couldn't tell from the numbers on the choke horn.
Its on a 355, and what its doing is it will idle fine, but its running crazy rich, to the point of burning my eyes if im in the garage while its running. also, if you try and crack it, its just loading up. timing is set @ 15 deg initial running a pro billet msd w/ 20 deg total advance, so the motor should be seing around 35 total if it would ever spin up.
How do you baseline a carb, as in what should the block be set at, the accel pump arm adj, and anything else? i have the metering block screws out 1 1/4 turns from full in, and am not messing with anything else. i'm basicly carb stupid, i always had my grandpa do mine, i mean i can make little changes, but i need to figure out what to do, i think 4 other people have had their hand in it, so who know what jets are in it, or what if anything they messed with. i need to get it running decent enough to hit it a bit to see what all it needs. Any help would be great guys, i'm lost!
thanks matt?
