OPERATION
Carburetion
Proper carburetor adjustment is critical, since a mixture too lean (too much air, too
little fuel) will result in overheating of the combustion chamber causing pre-ignition
of the fuel. This results in piston burning, bearing failure, or complete engine fail-
ure. A lean mixture can be the result of fuel line restrictions, foreign matter in the
carburetor, clogged fuel filter, etc.
A mixture too rich (too much fuel, too little air) is also unfavorable because it can
foul plugs and cause generally poor engine performance.
All carburetors have been pre-set at the factory for adequate fuel supply. Higher
altitude operation may require different adjustment and settings.
RMK models are pre-set to operate at altitudes of 6000-9000 feet above sea level.
WARNING
Carburetor adjustments must be performed by your dealer, since mistakes can re-
sult in possible operator safety hazards as well as serious engine damage.
Remember, correct setup provides engine RPM within its given power band at full
throttle settings and also provides maximum efficiency and operation at all other
throttle openings. Your dealer has the training and tools required to perform any
adjustments for you.
WARNING
Engine damage may result if jetting or clutching is wrong. Never service clutches
yourself. See your dealer.
