THROTTLE BODY CLEANING AND
INSPECTION
"
• Clean all passageways with a spray-type carburetor cleaner
and blow dry with compressed air.

• Check following items for any damage or clogging.
* O-ring * Fuel injector filter
* Throttle shaft bushing and seal * Injector seal

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 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.
