CLEANING

Some carburetor cleaning chemicals, especially dip-
type soaking solutions, are very corrosive and must
be handled carefully. Always follow the chemical
manufacturer's instructions for 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
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.
Do not use wire to clean the passageways, valve seat,
and jets. If the components cannot be cleaned with a
spray-type cleaner it may be necessary to soak the them
in a dip-type cleaning solution. Always follow the chemi-
cal manufacturer's instructions for proper use and
cleaning of the carburetor components.
After cleaning, reassemble the carburetor with new O-rings.
Replace the removed O-rings with new ones.
