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.
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 bracket away from engine. This will slow
the engine. Make sure to hold plunger into solenoid during
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. After reaching proper idle speed, tighten M8 nut to secure
solenoid mounting bracket.
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 Ad-
justment in Honda Engine Manual).
8. Replace engine linkage cover.
