DASH POT
1) Warm-up the engine sufficiently, and check that the idle
speed is as specified.
2) Under the non-loaded state, turn the throttle lever by
hand and increase engine speed until the end of the dash pot
is off the throttle cam.
3) Gradually return the throttle lever, and read the engine
rpm when the throttle cam contacts the end of the dash pot.
Engine rpm 2,800 - 3,400 rpm
4) If the engine rpm is not within this range, loosen the lock
nut of the dash pot, and turn the dash pot until this specifi-
cation is satisfied. After adjustment, tighten the lock nut
securely.
5) After adjustment, race the engine and make sure the idle
speed returns correctly to the idle speed as the throttle is
released.
