engine won't stay running. If I leave choke on, and move throttle by hand, I can keep engine running. I 1st time in 25 years that storage was done incorrectly. Had some gum up issues in the carb., and removed carb. to replace some old washers, and clean out gum deposits. Carb. seems clean, all orifices have carb. cleaner coming through. Not sure if governor is now working, or did I put linkage back in all same position. Manuel does not show any of this. Anybody have a picture, or ideas?
