This unit used three different Idle/Throttle Control Valves, depending on when it was manufactured. Make sure to look at the photos and match up your style before ordering!

  • Older units used the "Bullwhip" cable style throttle control
  • Newer units use the "Airline" throttle control with hollow, plastic/nylon tubing
  • The 1312100382 was rarely used, and uses an "arm" connected to it and the engine governor.
