just got my bird home and the guy i bought it from put a preformer intake and holley carb on it.
apparently he has less of a clue than i do about adjusting them. the choke wont kick off and it idles really fast.
anyone know of a website that can explain all of the adjustments and how to do them?

thanks

which model Holley? I'll help you find what you need.

There is a screw behind the choke, facing towards the front of the car, on the passenger side of the carb that adjusts the choke release. My guess is the previous owner screwed it in to tight and it's "stuck" in a groove it created since the cam it rides against is plastic. Also your idle adjustment (driver side near the base plate on the carb) might be set to high. You can turn the screw counterclockwise and see if the throttle bracket rotates back towards the firewall. Your timing could be to far advanced also. Personally I would back the choke screw off so the choke won't stay on long (is it electric or a mechanical choke). Once this happens slowly tighten the screw until you get to a point you can live with. Also check for binding of the choke butterfly. I would than back off the idle adjustment screw until the throttle bracket on the driver side of the carb doesn't move anymore. If you car dies than slowly turn the screw back in until you get an acceptable idle with the car in Drive (with brakes on of course). Ideally you should pull the carb and verify where the primary butterflies are in relation to the transition slot but that is a whole new can of worms. The stuff listed above should get you started and it only requires a screwdriver (except removing the carb).

is there anyway you can take pics of the setup and we can walk you through all of it

ok i got pictures of my carb and intake setup. friend told me it was a holley, its an edelbrock preformer carb
whats the best way to tune carbs? do fuel mixture first then idel and the choke? what order?

thanks for the help

The Performers are mostly bolt-on and run carbs, somebody must have messed with it. Its pretty easy to go back to original settings though. Which carb have you got?

Chondro,

You should set the idle first. Once you have that set where you like (it will be different depending on your cam) then adjust the fuel mixture. You should turn the idle mixture screws in all the way. Careful to just snug them, anything else may bend the needle. Then back them out 2 1/2 turns. From there, while looking at a tach, turn them in until the idle starts to decline.

Check and make sure your choke linkage is not catching on the air clearner. That is a common reason for not kicking down to low idle.
