Help! Injector pump problem.

Cranked my 1965 Case 1150 dozer Saturday after sitting idle for about a year. When it cranked, the engine is at max RPM's. The throttle had no effect on engine speed. I was told the governor was stuck. Also was told that I could either tap on the inj. pump and if that didn't work, to take a nut out of the end of the pump and there will be a "fuel rail" that is stuck. Tap the rail and it should give control back to the throttle. I need help/verification here. Anyone got ideas or had to fix this problem before?

How did you get the over revving engine to stop?

(This may have a bearing on whether the "rack" is stuck, or not.)
 
I just repaired a Case 830 inline pump for the same trouble. On ANY brand inline pump, only takes ONE sticking, or stuck plunger to keep the rack from freely moving as it should. Take the round two flat cap off the front of pump, remove the screw with shims in the rack end if it has one. Now remove one of the side cover screws and thread it into the rack for a "handle". Loosen ALL lines at the injectors so engine will not start. Now with a starting jumper switch, or helper crank the engine while by hand pushing/pulling on the rack bolt, if you are LUCKY it might free up after engine/pump have made several revolutions, if not, pump needs to come off for more serious attention. DO NOT BEAT ON THE RACK!! That can break gear segment teeth inside, making problems worse..
 
I loosened the first two injector lines at the pump and the engine died. I tried several ways to smother it down but it wouldn't die.
