5-12 FUEL SYSTEM
CLEANING
• 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. If necessary, soak each cir-
cuit in a dip-type cleaning solution to loosen dirt and varnish.
Dry the carburetor body using compressed air.
• After cleaning, reassemble the carburetor with new O-rings.
Some carburetor cleaning chemicals, especially dip-
type soaking solutions, are very corrosive and must
be handled carefully. Always follow the chemical man-
ufacturer’s instructions on proper use, handling and
storage.
Do not use a wire to clean the jets or passageways. If wire is used, the jets and passageways
may become damaged. If the components cannot be cleaned with a spray-type cleaner it may
be necessary to soak the components in a dip-type cleaning solution. Always follow the chemi-
cal manufacturer’s instructions for proper use and cleaning of the carburetor components.
Replace the removed O-rings with new ones.
