SERVICE INFORMATION
FUEL SYSTEM
GENERAL
• Bending or twisting the control cable will impair smooth operation and could cause the cables to stick or bind, resulting in loss of
vehicle control.
• Work in a well ventilated area. Smoking or allowing flames or sparks in the work area or where gasoline is stored can cause a
fire or explosion.
• Before disconnecting the fuel feed hose, relieve fuel pressure from the system (page 7-4).
• Do not snap the throttle valve from full open to full close after the throttle cable has been removed. It may cause incorrect idle
operation.
• Seal the intake port with a piece of tape or a clean cloth to keep dirt and debris from entering the engine after the throttle body
has been removed.
• Do not damage the throttle body. It may cause incorrect throttle valve operation.
• Prevent dirt and debris from entering the throttle bore and air passages after the throttle body has been removed. Clean them
using a compressed air if necessary.
• Do not loosen or tighten the white painted nut and screw of the throttle body. Loosening or tightening them can cause throttle
valve and idle control failure.
• Do not apply commercially available carburetor cleaners to the inside of the throttle bore.
