Carburetor/ tune up help!

My baby is about to get her first tune up, my quick question was, does it matter if I go to any shop? Because most cars now are more electrical, technology wise, since mine is carburated, I want to know that any shop I go in will know how to take care of her, I'm in southern California btw for if anyone knows a good tune up shop

Re: Carburetor/ tune up help!

You might find it challenging to find a shop that has techs familiar with the CCC Q-jet.

Even if you do take it to a shop for everything, you shold probably make an effort to understand what makes the carb unique and why "most carb problems aren't" (an old Smokey Yunick phrase.) Especially since you gotta smog.

If the car seems to run properly, you might want to give it a quick rundown of how worn / corroded the terminals in the cap / rotor are, whether the EGR valve stumbles the idle (functional EGR is important,) spray down the carb w/ some light duty carb cleaner to help keep the choke from sticking, check the plugs to see whether it's rich / lean, and if you can put a scan tool on it to see how lively the O2 sensor is, whether you've got a good TPS signal and dwell numbers.

Keep reading and enjoy.
