How do I adjust governor?

I had to replace the governor control arm on my 18hp(single cylinder) B&S engine. I also replaced the throttle and governor springs. The engine runs at pretty much full throttle all the time. How do I adjust?

Locate the governor shaft where it comes out of the engine block. Loosen the arm that is attached to the shaft. Hold the throttle on the carburetor to the wide open position and note which direction the arm attached to the governor shaft moves. While holding the throttle wide open rotate the governor shaft in the same direction it would turn to open the throttle, turn it until it stops. Tighten the arm back down to the governor shaft. Thats the procedure for making the static adjustment on any internal governor, horizontal or vertical.

Now setting the top governed engine speed will be different depending on Make, Model, Brand etc........

Good Luck.
