Fuel Control: Notes

All models use a 2-barrel Stromberg-style downdraft carburetor with mixture control (duty) solenoid, automatic choke and piston-type accelerator pump. Carburetor integrates a low speed (primary) barrel and a high speed (secondary) barrel, while using a common fuel bowl. Idle speed is set with idle speed screw. An evaporative fuel system keeps fumes from venting to the atmosphere.
