Carburetion
NOTICE: Making non-recommended adjustments could result in vehicle or
engine damage as well as denial of warranty claims. We recommend
that all carburetor adjustments be performed by your POLARIS
dealer.
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, for-
eign 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.
