Throttle Slide Adjustment
All Models Except Mach Z/Z LT
For maximum performance, correct carburetor
throttle slide adjustment is critical.
The following method should be used with engine
turned off:
–
Idle speed
screw must be completely un-
screwed. It must not contact throttle slide.
Turn the
idle speed
screw clockwise until it con-
tacts the throttle slide then continue turning 2 ad-
ditional turns.
Repeat on the other carburetors. This will ensure
identical throttle slide preliminary idle setting. Re-
check carburetor synchronization. Adjust idle by
turning all idle speed screws of the same amount.
All Models Except Mach Z/Z LT
Throttle slide must be flush or 1.0 mm (.040 in)
lower than the top of carburetor
oulet
bore (en-
gine side).
