Flooded Engine

If the engine won’t start after several pulls on the

starter rope the engine is probably flooded.

To clear a flooded engine:

1. Move the throttle lever to “STOP” and turn off the

fuel valve.

2. Remove and dry the spark plug. When re-installing

the plug, thread it in by hand until it seats. Then

tighten it an additional l/8- l/4 turn with the spark

plug wrench to compress the washer.

3. Move the throttle to “HI”, turn on ‘the fuel valve

and repeat steps 3-5 under “Starting the Engine”.

Stopping the Engine

1. Release the drive clutch (S-XAM TYPE only).

2. Move the throttle lever to “STOP” and turn off the

fuel valve.

High altitude operation

At high altitude, the standard carburetor air-fuel

mixture will be excessively rich. Performance will

decrease, and fuel consumption will increase.

High altitude performance can be improved by

installing a smaller diameter main fuel jet in the car-

buretor and readjusting the pilot screw. If you always

operate the rotary mower at altitudes higher than

6,000 feet above sea level, have your authorized

Honda Rotary Mower dealer perform these carburetor

modifications.

Even with suitable carburetor jetting, engine horse-

power will decrease approximately 3.5% for each

1,000 foot increase in altitude. The affect of altitude

on horsepower will be greater than this if no carbure-

tor modification is made.

* Operation of the mower at an altitude lower than

the carburetor is jetted for may result in reduced

performance, overheating, and serious engine

damage caused by an excessively lean airffuel mix-

ture.
