Is the carburetor and all of the linkage stock? If so....

With the carb at warm idle and the trans lever full forward, adjust the top rod so that the rear of the slot rests against the back side of the throttle stud. Be sure there is a spring to pull the linkage forward. The linkage should start to move rearward as soon as the throttle is opened, no lost motion.

From the initial setting, the linkage can be adjusted to tune the part throttle upshift points to suit the individual. If the trans will kickdown at WOT from top gear at around 40 mph, the adjustment is OK.

The top lever on the transmission should be full forward when the carb is at warm idle.

Have someone floor the gas and check to see if throttle cable pulls the carb open all the way.
