Holley Choke Fast Idle Cam Red 4150 4160 Carby Carburettor Electric / Auto Choke

• Fast idle cam helps restore correct cold-idle speed and step-down behaviour on Holley carburettors.
• Correct cam profile supports smoother warm-up and better throttle response when the engine is cold.
• A genuine-style replacement is a handy service part for worn or missing cams.

The fast idle cam works with the choke linkage to hold the throttle slightly open when cold, then step the idle speed down as the choke warms up. If the cam is worn, cracked or missing the engine can idle too high, too low or behave inconsistently during warm-up. Fitting a replacement is a simple fix that can make a noticeable difference in cold-start manners.
