I have a 66 cub, and the carb has been replaced with a zenith carb off a 
185X model... complete with breather hose adapter for the larger intake.. 
etc.

Is yours the oem cub carb? or a zenith?

When you replaced the throttle shaft, did you also replace the shaft seals / 
packing?  Choke packing?

As the other poster said.. see if yuo get max rpms by manually actuating the 
throttle.. not letting the governor do it.

Of course.. if it is very righ, or the float is stuck / not set right.. you 
could be flooding out.. etc.

I started with 1 turn on the main and adjusted from there by ear, and 
checking for engine stumble..
