My trans am has a stock rebuilt Rochester quadrajet 750 cfm 4bbl carb. It desperately needs a tune up but I have no clue about how to do anything with carbs. wondering if anybody here either has an extra carb for sale or could help me give it a tune up. I’d compensate for the time it takes and whatnot.
anyone?
What year is the carb. and does it have the electric solenoid for the mixture on top or is it an older unit
Why does it desperately need a tune up?
Quite a few details missing, how is purchasing another carb that isn’t setup for this car going to help?
Does it need a rebuild?
Lull in power?
Tune way off?
Failure to start?
Specifics make the world go round.
Sorry…I don’t know jack shit about carbs lol. I just know its running rich, its like 6 years old, 750 cfm Rochester Quadrajet 4bbl mechanical choke. It tends to diesel when I shut it off after its been running for a bit. and it is KILLING me in gas. Normally a carbed 305 does a little better than like 12 mpg lol.
6 years old, lol. That’s not old.

How high is your idle speed?
Any hesitation/driveability issues?
What is your timing set to?
It’s not like you can just sit around expecting people to fix stuff for you. It’s a simple thing, and if you plan on keeping the car something you should learn.
