Does anyone have an experience with the governor control system on the KE70/5? It seems like I may have an issue with that but I don't know of a good way to test it. I've noticed that the "fork" that connects the the IP rack is quite loose (you can move the fork really easily back and forth about 3/4")when the pump is removed. In fact, the spring that is attached to the throttle handle linkage inside the gear case only starts to tension up at full throttle and it tends to follow the throttle handle rather than the governor. Shouldn't the governor be trying to put the rack at the full position when the engine is off? I'd like to think there is something wrong here, but the engine seems to respond to throttle commands just fine although it's hard to tell if the governor is compensating at all. I guess I need to know if the governor spring is just there to compensate for a "hyper-extended" throttle handle or if the spring should always be under tension during normal operation (?).
The service manual tends to shy away from governor specifications and only makes statements like - if part "X" of the governor system is "bad" then replace it which is of very little use to me. Oh, and the spring is designated as "specific to the application" in the parts manual so I wouldn't even know what one to replace it with if I thought it was bad. Also, my electronic copy of my service manual is missing Figure 10 which diagrams the governor parts which is inconvenient at this point.
It would be great to know what the position of the rack is at any given time, but I don't know of a handy way to do this. I even thought of mounting a small battery powered wireless camera in the voids in the gearcase to see what is going on in there but that is kind of a crazy impractical idea - and I don't believe the signal would travel through the metal anyway (Faraday cage?). Getting wires out for a slide resistor and such things also seems difficult. Any suggestions?
