I had to do some adjusting on the throttle cable where it connects to the gov. arm, but I dont recall if I moved the arm back or foward.

The cable will pull the lever on the governor till it hits a positive stop, that can be adjusted by the bolt on top of the governor. With a helper present, loosen the cable clamp, and manually pull the lever till you reach the desired RPMs, adjusting the bolt stop as necessary. When the RPMs are where you want them, and the throttle lever in the full/high position, tighten down the cable clamp.
If the spring is weak, it will also not allow you to reach high RPMs.

Put a new spring in the gov. The spring opens the throttle & the flyweights close it.
