OPERATION
Carburetion
Proper carburetor adjustment is critical. A lean mixture (too much air,
too little fuel) may result in piston burning, bearing failure, or
complete engine failure. A rich mixture (too much fuel, too little air)
may foul plugs and cause generally poor engine performance.
A lean mixture may be caused by things like fuel line restrictions,
foreign matter in the carburetor, or clogged fuel filters. A rich mixture
may be caused by snow build-up on the pre-filter in the air intake
system. Either condition may be caused by improper carburetor
adjustment.
All carburetors have been preset at the factory for adequate fuel supply.
Higher altitude operation m ay require different adjustments and
settings. NOTE: RMK m odels are preset to operate at altitudes of
6000-9000 feet above sea level. See page 118 for more information.
Your dealer has the training and tools required to perform any
adjustments for you.
Carburetor adjustments must be performed by your dealer, since
mistakes may result in possible operator safety hazards as well
as serious engine damage.
