Cracked the frame which also cracked the engine block. Replaced the block and have started the engine and it idles. but cannot throttle up. have pulled the timing cover and checked the linkage and all appears to be free and functioning. wondering if i have the return spring in the correct location. does anyone have info on how the spring should be attached.

Only simple suggestions:
You are sure the linkage is connected?
Have you tried operating it by hand on the engine itself?

With the engine running, the same check, I don't see the rack moving. It just stays in idling position. My suspicion, is that I'm either missing a spring or have the govenor spring connected to the wrong tab on the govenor control lever. The parts manual does not show the same lever I have.

Had hoped someone who knew the answer would have helped by now. Have you checked to see if there is anything on youtube on say adjusting the throttle linkage? I doubt it but...might be. ....
