Automatic Choke Carburetors (Stepped Cam)
NOTE:
Make initial idle speed setting by turning throttle stop-screw in 1 1/2 turns from closed throttle valve position (setting must be rechecked when carburetor installed on engine.)
Position fast idle cam follower on highest step of cam, hold cam follower against cam and check clearance between end of throttle stopscrew and idle stop tang on throttle lever. If clearance not correct (see Specifications ), adjust by bending cam follower toward or away from fast idle cam.
