Idle Micro Switch
- Warm engine to normal operating temperature. Disconnect micro switch coupler and connect ohmmeter to idle micro switch. See Fig 1 .
- Run engine at idle and make sure ohmmeter indicator is at zero. Connect tachometer to engine. Increase engine speed gradually, checking that ohmmeter indicates infinity when engine speed is 1500-2400 RPM.
- If engine speed is not within specified range, adjust idle micro switch lever. See Fig 2 . Bend lever down if engine speed is below range, bend up if engine speed is above range.
