engine, overheating and even cause more serious damage.
The gasoline is fed into the carburetor from the fuel tank and fuel filter. The fuel filter can filter out
impurities mixed in the gasoline and oxides in the fuel tank. If the quality is defective, some impurities will
enter the carburetor through the
fuel filter. In addition, gasoline contains components capable of
forming gelatinous substance, which will condense gelatinous substance after a long time of
deposition to attach to components of the carburetor (such as main metering jet), oil way and
the surface of float chamber. Air is fed into the carburetor by way of air filter. Based on the
consideration that intake resistance shall not be too great and other factors, filter device shall
not be too dense, hence some tiny impurities in air will still enter the carburetor via the air
filter.
The carburetor shall be cleaned on a clean site. Clean the external surface of the carburetor,
and clean the internal parts with special carburetor cleaner or industrial gasoline. Pay attention
to clean gasoline gel besides impurities on surface of the parts. The cleaned part shall be
blown with compressed air, and shall not be wiped with cloth or paper to avoid secondary
pollution. It is forbidden to poke through clogged hole by hard object such as steel wire, to
prevent hole diameter from changing to cause the change of carburetor performance, but it
shall be washed off with gasoline or compressed air.
