I have a waukesha engine, model L7042GU, and i am having some problems with it. it keeps hunting. so far we have done everything that we can mechanically, now we are to the electrical part. i think it might have something to do with the governor, but not sure. after i took the arm off the acctuator it worked fine, so pretty sure its the governor. what tests can i do to make sure that it is the governor, and if so then what is the reccomended way of fixing this problem? any other ideas of what this could be?
