Idle Switch
- To check and adjust idle switch, loosen upper left bolt on throttle valve housing. Attach Protractor Pointer (3084 ) under bolt. Attach Protractor (3084 ) on primary throttle valve shaft, removing shaft nut if necessary. See Fig 1 .
- Disconnect wiring to switch. Connect ohmmeter between terminals of switch. Set protractor so pointer is on "0" degrees. Open throttle to 20 degrees and close it slowly. Switch must have continuity from one degree to 2.5 degrees when opening.
- If reading is incorrect, remove throttle valve housing. Loosen idle switch mounting screws and adjust switch position. See Fig 2 . Switch must close (continuity) before throttle control reaches idle stop position.
