Thanks Ian, I did get the rack to final move via the oil filler cap and a wire hooked around the fuel rack pin. This is the same route I used to hook it to the linkage. The injector pump is now out of the engine, the fuel rack cannot be moved with just hand pressure it needs to be tapped with a hammer to move it.
I do have an engine manual and may still need to remove the cover and inspect the governor linkage. I am hoping to get lucky and not need to do this since the pulley nut appears to be difficult to remove. If I do have to remove the cover does the water pump need to be removed?
