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 failure. A lean mixture
can be the result of fuel line restrictions, foreign matter in the
carburetor, 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.

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.
Carburetor adjustments must be performed by your deal-
er, since mistakes can result in possible operator safety
hazards as well as serious engine damage.
