Air/Fuel Mixing & Controls

Tune Your Idle: NOS Carburetor Controls & Mixture Parts

A vintage engine is only as good as its air/fuel mixture. If your classic is hard to start on cold mornings, stalls at stoplights, or idles roughly, the small control devices on your carburetor are likely to blame.

The Precision of NOS Carburetors require precise vacuum signals and thermal reactions. Modern "generic" replacements often lack the correct calibration. At Old Car Parts NW, we stock authentic NOS (New Old Stock) and NORS components for Holley, Rochester, Carter, and Autolite systems.

  • Choke Thermostats: The bi-metallic coils that automatically close the choke for cold starts.

  • Vacuum Pull-Offs (Choke Breaks): Essential for preventing flooding by slightly opening the choke once the engine fires.

  • Dashpots & Solenoids: Stop the engine from stalling when you suddenly lift off the gas pedal.
