MAINTENANCE

IDLE SPEED

IDLE SPEED

Check throttle link mechanism and carburetor
throttle valve for smooth operation.

Connect a shop tachometer to the engine.

Start and warm the engine.

Check engine idle speed:

•

950 to 1050 RPM in neutral

•

900 to 1000 RPM in gear

IMPORTANT:

Check and/or adjust idle speed

after the engine speed has stabilized.

If idle speed is out of specification, adjust as fol-
lows:

Turn the throttle stop screw:

•

Clockwise: Engine speed increases

•

Counterclockwise: Engine speed decreases.

IGNITION TIMING

IMPORTANT:

Before checking ignition timing,

make sure idle speed is adjusted within specifica-
tion.

Start and warm the engine.

Connect a shop tachometer and timing light to the
no. 1 cylinder.

Check the ignition timing while operating the
engine at 1000 RPM.

Ignition timing:

•

2° BTDC @ 1000 RPM
