CARBURETOR 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 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
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.
%
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 al-
low them to soak. Always follow the chemical
manufacturer’s instructions for proper use and cleaning
of the carburetor components.
• After cleaning, reassemble the carburetor with new seals and
gaskets.
