The "throttle" is a spring arrangement that pulls on the rack pin to move the rack forward (more fuel) and the centrifugal governor pushes it aft via a lever. The governor and "throttle" should exert force on the rack pin. Basically, the IP injects enough fuel to balance the centrifugal and spring forces.
Your picture makes it look like the throttle/spring has disconnected from the rack pin. But maybe I'm not seeing it right. If that were the only problem, the engine should still start and idle.
Ok, I'm with you on everything except quoted here. Now the governer exterts rearward force on the pin by a level it looks like. I can see that by looking in the hole how it would push the pin on the rod backwards.
As for the throttle spring that's the big spring in the photo, the one on the outside correct? It hooks around the throttle rod, I assume that's what that is. But in no way does it touch that pin. The item marked 6 in the picture is the end of thats spring loop around the throttle rod. Should that be wrapped around that pin on the rack? Even if that's the case I have no idea how it would stay on. There is no hook on that rack pin to hold it in place.
I put a pick in there and can move it around and inbetween the rack pin and that throttle rod. There is just enough space to pass the pick. So if that throttle spring is suppose to go over the rack pin it seems like it would just slip off... :confused3:
No warrenty. Bought it used with 32hrs, only has 39 hours now. I'm the guy with the broken tach too. Starting to get a little upset with this tractor.
