WARNING
Protect eyes from contact with cleaner. Take
appropriate safety measures during these
procedures. Safety glasses and chemical
resistant gloves are required. Should you get
cleaner in your eyes or if you swallow cleaner,
seek medical attention immediately.
Carburetor cleaners can be extremely caustic.
Extended periods of soaking can loosen the
adhesive sealer on the passage drill-way plugs.
Do not soak rubber or plastic components or O-
rings in caustic cleaning solutions. Irreparable
damage may occur. Do not use agitator-type
carburetor cleaning equipment.
Rubber parts must be cleaned with mild
detergent and hot water only.
Thoroughly clean the carburetor body, jets, and all
passages with carburetor cleaner or electrical contact
cleaner.
If the carburetor is extremely dirty or contaminated with
fuel residue and varnish, soak for short periods only in
carburetor cleaner, and rinse in hot water.
Replace the jets if they have a buildup of fuel residue or
bacterial growth that cannot be removed. Even a small
amount of residue will reduce the flow characteristics of the
jet.
Verify all passages and jets are unobstructed by spraying
electrical contact cleaner through the passages.
Use low pressure air to dry carburetor body and all
components.
