  5. 1946 Choke System
How the choke system works on a 1946, 1 barrel.

When the engine is cold the choke valve is closed and using a linkage hooked to the choke lever, the fast idle cam is pulled up, putting the idle screw on a raised step. This opens up the throttle slightly causing the RPM to pick up.
