SERVICE INFORMATION

GENERAL

• Bending or twisting the control cables will impair smooth operation and could cause the cable 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 disassembling the carburetor, place an approved gasoline container under the carburetor drain plug, remove the drain plug and drain the carburetor.

• When disassembling the fuel system parts, note the locations of the O-rings. Replace them with new ones on reassem­bly.

• After removing the carburetor, wrap the intake port of the engine with a shop towel or cover it with a piece of tape to prevent any foreign material from dropping into the engine. Be sure to remove the cover when reinstalling the carbure­tor.

• 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 driveability.
