THROTTLE BODY CLEANING

#
Some carburetor cleaning chemicals, especially dip-
type soaking solutions, are very corrosive and must
be handled carefully. Always follow the chemical man-
ufacturer's instructions on 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.
