THROTTLE BODY 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 passageways with a spray-type carburetor cleaner
and blow dry with compressed air.

Do not use wire to clean passageways. Wire can dam-
age 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 throttle
body components. Do not apply carburetor cleaning
chemicals to the rubber and plastic materials.
