Oil Pump Adjustment Procedure
250 and 300 Engines
1. Before adjusting the oil pump,
check engine idle RPM and car-
buretor adjustments which are
found in the owner’s manual sup-
plement.
2. Remove electronic throttle con-
trol (ETC) cover.
3. Loosen throttle cable jam nut and
turn adjuster in or out until there is
1/16″ (.16 cm) of throttle lever
travel before throttle slide starts to
open.
4. Place very slight pressure on the
throttle lever until all freeplay is re-
moved from throttle cable (to the
point where the carb slide is just
starting to rise).
5. Loosen locknut. Turn adjuster in
or out until all freeplay is removed
from oil pump cable (the point
where the oil pump arm is just
starting to move off of its stop).
The pump stop keeps the pump
arm from rotating any farther
down than the idle position so no
visual alignment of marks is nec-
essary. Tighten the locknut
