That machine has a Roosamaster injection pump. I am suspecting you had two different issues. One being that chemical got in the fuel control pivot point and made it stiff to operate and eventually broke both the cable and lever. Secondly, the plastic cushion ring for the governor weight assembly got old and started breaking apart. The little pieces float around in the pump and occasionally get in places the should not be and cause it to run erratically. This usually is paired with the pieces lodging in the check valve in the return line of the pump. This raises the housing pressure and the engine dies or starts lacking power. However if at some point that check valve was knocked out of the fitting to allow the machine to continue to run parts in the injection pump start wearing metal to metal. There may even be a point were rotating pieces start coming off inside the pump. That could very well break things. We will see if Dieseltech chimes in with any more details. I would ask the injection pump shop if the return line check valve was intact on the pump.

In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
