Dexta No Throttle

[Tractor Pat]

I have just resurected a Super Dexta that has been barn stored for at least 10 years. It eventually started and seems to run well, but the throttle doesn"t work, it revs all the time and the only way of adjusting the RPM is with the stop lever. It is a Simms mechanical governed pump so presumably the governor is seized. Any ideas for a qucik fix, or which part of the pump to strip?
Many thanks,
Patrick

It sounds like the "rack" in the injection pump is seized.

Take the side cover(s) off of the pump and try some loosen juice.

Also check to see if the butterfly in the intake manifold is not stuck open.(Throttle control)
