Tim. On your H the governor is located on the left forward side of the engine. It's that sort of square looking box that has the tube running off the top, back to the carb. It really has two functions, the first being to maintain what ever engine speed you've set with the throttle. In other words, as the load on the engine increases it will open the throttle in the carb to try and maintain the set rpm. Of course once the governor has opened the throttle wide open it's done all it can do and any further increase in loading will cause the rpm's to decrease. A secondary function is to not let the engine exceed it's maximum rated speed when you pull the throttle all the way back with no load on the engine. This speed is sometimes refered to as high idle speed or max governed speed. It works very basicaly by balancing a pair of rotating flyweights in the governor against spring tension. At any engine rpm the weights are rotating and trying to sort of fly out with centrifigual force which is restrained by the spring. As the engine slows down because of increasing load the weights move in, which in turn opens the throttle valve to try and maintain set rpm. I think that's right, somebody correct me if I'm wrong. Surging is basically when the engine rpm varies up and down and never really settles down to a constant speed. Generally caused by either some worn parts in the governor, slop in the linkage, or just not adjusted correctly. And while I'm thinking of it, does anybody know the proper way to adjust the springs on an H there where the rod from the hand throttle bolts to the bellcrank on the engine head under the hood? And what are they for? Glad everything on your H is working fine. Remember, if it ain't broke, don't fix it! But you can be assured that if something does go wrong, there are plenty of people here that have probably had the same problem and are more than willing to help.
