The fuel cut off lever should be full forward to be in “Run”.
The throttle linkage is at idle when full forward. See Picture.
If your throttle linkage is not loose and you had a run away, I suspect there is an issue with the governor. I would recommend draining and replacing the oil as the first easy step. Instructions are on page 40 of this document:

Since you pulled the stop lever from the full fuel position the rack could be jammed in the no fuel position. Since there is no mechanical connection between the throttle linkage and the rack you may have to remove the side cover to free it up. If you had a seemed runaway with the throttle in the full fuel position you may be ok, but if the throttle was at idle or half you do have a governor problem.

yes success yesterday. Finally got some time to dig into the injector pump.
removed oil filter and housing with spacer. Now I can access all three screws on governor. I cracked open the case, and it was bone dry. Rusty and seized. Everything . No large ball bearings in mine. There are 4 square blocks that pivot and a cylinder with a small bearing inside. The fuel cut off piston was stuck out.
i cleaned, lubed. And reassembled. And she fired right up! :yahoo:
Thanks for the support.

was there the correct level of oil(15w40) in the pump? It might be a good idea to run it a little and drain the pump to see if there is fuel in there mixed with the oil. The reservoirs are small and refilling can take patience, overfilling is easy.
