If you don't think it's ever been rebuilt it couldn't hurt. They are a little complex so if you can find someone who has done them before you might be better off , I'm acually waiting for my father to do mine now because he's done a ton of them in the past .

Steps to diagnosing and repairing carburetor problems when your car is running like crap:

1) Fix whatever is wrong with your ignition system, fuel delivery, and sensors.

2) Step #2 is not needed 75% of the time.
