CARBURETOR CLEANING
!WARNING
Clean all jets with a spray-type carburetor cleaner and
dry them using compressed air.
Clean all circuits of the carburetor thoroughly-not just the
perceived problem area. Clean the circuits in the
carburetor body with a spray-type cleaner and allow each
circuit to soak, if necessary, to loosen dirt and varnish.
Blow the body dry using compressed air.
!CAUTION
after cleaning, reassemble the carburetor with new seals
and gaskets.
Some carburetor cleaning chemicals, especially
diptype soaking solutions, are very corrosive and
must be handled carefully. Always follow the chemi-
cal manufacturer’s instructions on proper use, han-
dling and storage.
Do not use a wire to clean the jets or passageways.
A wire can damage the jets and passageways, if
the components cannot be cleaned with a spray
cleaner it may be necessary to use a dip-type clean-
ing solution and allow them to soak. Always follow
The chemical manufacturer’s instructions for proper
use and cleaning of the carburetor components.
