foreign substance, clogging or damage.
Check the tip of the float valve, where it
contacts the valve seat, for stepped wear or

Check the operation of the float valve.
CARBURETOR BODY/JETS
INSPECTION AND CLEANING
Check carburetor body and each jet for wear
or damage.
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.
＊
● 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.
● 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 cleaning solution and
allow 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.
