diaphragm (throttle opener) and connecting hoses and wires. The

throttle opener opens the primary throttle valve when air conditioner

is operated at engine speeds of 1000-1200 RPM to maintain smooth

engine operation.

IDLE COMPENSATOR TEST

Remove air cleaner cover and filter element. When bi-metal

temperature is below 149

F (65

C), valve should be closed and no air

leakage should exist when vacuum is applied to tube. Bi-metal valve

should be open when temperature exceeds 159

F (69

C). If valve does

not function as described, replace valve.

ALTITUDE COMPENSATOR TEST

NOTE: Altitude compensator can only be checked at altitudes of

1640-4920 ft. (500-1500 m).

1) Remove air cleaner and start engine. Engine should idle

smoothly. Place finger over slow port inside carburetor bore (located

on right side of rear bore). With slow port covered, idle speed should

drop.

2) If idle speed does not drop, stop engine and remove

compensator valve. With compensator valve removed, blow through

drilled passages.

3) Air should pass through valve from both passages at

altitudes of 1640-4920 ft. (500-1500 m). If not, replace altitude

compensator valve.
