ADJUSTING THE IDLE SPEED

IMPORTANT: Adjust the idle speed

•Only if the idle speed becomes too high

•If engine idle speed will not regulate (engine idles and speeds up again and again).

1.Turn Auto-Idle switch off. Start engine. Allow engine to warm up with no load for five minutes.

WARNING: Guard against burns. Hot muffler, exhaust manifold, and engine parts can cause severe injury. Use caution and remain alert when adjusting or using generator.

2.Hold plunger in solenoid body to manually engage solenoid and set idle speed.

WARNING: Always set the idle speed before turning on the Auto-Idle. If idle speed is not set, the large resistor on the control board may become hot. Heat from the resistor may damage the protective coating on the control board.

3.Slowly pull solenoid and bracket away from engine. This will slow the engine. Make sure to hold plunger into solenoid dur- ing this step.

4.With a volt meter, check the no-load output voltage at the 120- volt duplex receptacle. At proper idle speed (2680 minimum RPM) the meter should read 50-60 volts. Lower settings will cause the auto-idle to not operate properly.

5.Locate proper solenoid mounting bracket positioning. Line up solenoid body so that plunger will fully engage into body with- out any interference.

6.Turn Auto-Idle switch on. Make sure solenoid is engaged. When solenoid is engaged, the solenoid pulls plunger back into solenoid.

7.If the engine speed is too slow, the engine will want to “hunt.” When engine hunts, it speeds up and then slows down repeat- edly. When this occurs, increase engine speed by adjusting throttle stop screw on carburetor (refer to Carburetor Adjust- ment in Honda Engine Manual).
