[AT] Cub Carb Adjustment

[George Willer]

Karl,

Have you run the engine with the governor linkage disconnected?  If so, did 
it respond normally?  There can be an issue with the governor.

With the engine not running, disconnect the linkage from the arm ahead of 
the carburetor.  Adjust the clevis so that with the control lever full 
forward and the throttle wide open the pin should just slip in.
