• If the engine must be running to do some work, make sure the area is well-ventilated. Never run the engine in an
enclosed area. The exhaust contains poisonous carbon monoxide gas that may cause loss of consciousness and may
lead

death. Run the engine in
an
open area or with
an
exhaust evacuation system in
an
enclosed area.
• Bending or twisting the control cable will impair smooth operation and could cause the cable

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.

material from dropping into the engine.
• When disassembling the fuel system parts, note the locations of the O-rings. Replace them with new ones on reassem-
bly.
• The vacuum chamber and float chamber can be serviced with the carburetors combined.
• For carburetor synchronization, see page 3-12.
