distance between upper edge of choke valve and inner wall of air horn should be 3/16". (Use gauge T109-28). Adjustment can be made by bending lip on fast idle connector link.

open position. If it does not lock, re-check unloader adjustment. Closing the
throttle will release choker valve. Choker trip lever is notched out for this
setting. Choker mechanism must be absolutely free in any position.
FAST IDLE ADJUSTMENT: With throttle stop screw backed out until throttle valves
are completely closed, hold choke valve tightly closed and place .030" gauge
(T109-29) between throttle valve and bore of carbureter, side opposite post.
Adjust fast idle arm screw to rest on top, or upper step of fast idle cam
