How the governor works is: The airflow through the top or side of the engine depending on a horizontal or vertical crank, increases with the throttle and the airflow inside a cover hits against a flap of some sort
and the more you throttle and bring the RPM's up, the more air hits that flap and actually controls the carb and brings the throttle back down. This is just a way to save the engine from over- revving and blowing up. The only reason I like the governor system is, when climbing hills, it controls the carborator and keeps the engine from shutting down and actually helps you keep climbing. The governor doesn't come into play untill you actually get to half, to three quarters of a throttle or suddenly open the throttle all the way. YES, governors have their good pints and their bad>> GOOD--> Helps to keep engine from stalling when POWER, not speed, is needed. BAD--> Holds back the actual speed you could be doing while just giving you the ability to throttle and put the engine under pressure with out stalling it.With the governor on gokart, I can do 20 mph, without, I might be able to do 30 or 35 mph or faster, depending on how long I wanna keep my engine
Try this...... Go test a lawnmowers performance under stress. You will find that it will either climb up a brick wall or just sit there and spin its tires if you have the nose against a tree. Then, drive the same mower running directly off the carb linkage and you will see that there is no seemingly helping boost to get you up a hill or spin the tires if against a tree. It will just wanna stall out under pressure. I should know, been there myself LOL!!!!!
