CARBURETOR CLEANING

!
Some carburetor cleaning chemicals, especially diptype
soaking solutions, are very corrosive and must be
handled carefully. Always follow the chemical
manufacturer's instructions on proper use, handling
and storage.
• 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 per-
ceived 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.
7
Do not use a wire to clean the jets or passageways. A
wire can damage the jets and passageways. If the com-
ponents cannot be cleaned with a spray cleaner it may
be necessary to use a dip-type cleaning solution and
allow them to soak. Always follow the chemical
manufacturer's instructions for proper use and clean-
ing of the carburetor components.
• After cleaning, reassemble the carburetor with new seals and
gaskets.
