CARBURETOR CLEANING
!WARNING
y Clean all jets with a spray-type carburetor cleaner and
dry them using compressed air.
y 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
y 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.
