Carburetor Repair & Adjusting
If your older vehicle is hard to start, idles rough, stalls, or floods, the carburetor may need cleaning, repair, or adjustment. A mechanic disassembles, cleans, and tunes the carburetor so the air-fuel mix is right and your engine runs smoothly. Proper adjustment restores power and improves fuel economy.

Frequently asked questions
Does my carburetor need cleaning or a full rebuild?
A mechanic inspects it first. Light deposits often clear with a cleaning and adjustment, while worn gaskets, floats, or seals call for a rebuild kit. The inspection determines the right approach.
Why does my engine run rough or stall?
A dirty or misadjusted carburetor can deliver too much or too little fuel, causing rough idle, stalling, or flooding. Cleaning and tuning the carburetor usually restores smooth running.
Can a carburetor adjustment improve fuel economy?
Yes. Setting the idle and mixture correctly helps the engine burn fuel efficiently, which can improve mileage and reduce that strong fuel smell.
