The defect

The top end of the main spring that controls the governor in the speed control IS positioned by a two-piece seat. The inside of this seat can wear and cause the sleeve portion of the seat to separate from the washer portion. Consequently, the sleeve can drop down and lock the fuel rack in the fully open position, causing engine overspeed.
