Adjusting idle speed.
Idle Speed Adjustment
In cold weather the idle throttle stop
screw should be readjusted to get the cor-
rect idle speed. Adjustment should also be
made if the carburetor has been removed.
The correct idle speed is attained when
the engine operates steadily without missing
under no load.
To adjust the idle speed, start the en-
gine and loosen the idle throttle lock screw
"A" (Illust. 42). Turn in the idle stop
screw "B" to increase the engine speed
arid turn out to decrease the engine speed.
When the engine idles at the desired
speed, lock the idle throttle stop screw in
position with the lock screw.
