SERVICE INFORMATION
GENERAL
· 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.
· Bending or twisting the control cable will impair smooth operation and could cause the cable to stick or bind, resulting
in loss of vehicle control.
· Before removing the carburetor, place an approved fuel container under the drain hose, loosen the drain screw and
drain the carburetor.
· After removing the carburetor, cover the intake port of the cylinder head with shop towel to prevent any foreign mate-
rial from dropping into the engine.
· When disassembling the fuel system parts, note the location of the O-rings. Replace them with new ones on reassem-
bly.
· If the throttle cable was disconnected, perform the initial setting
(page 24-6)
after all carburetor adjustments have been
completed.
· If the vehicle is to be stored for more than one month, drain the float chamber. Fuel left in the float chamber may cause
clogged jets, resulting in hard starting or poor drive-ability.
·
