5. Using machinist's dividers or a drafting compass,
gauge the distance from the bottom of the cable
bracket to the bottom of the lever arm tip as
shown in III. 3. Note the exact position of the
divider on the bracket and lever arm. The divider
must be in the same position on these parts when
you perform the oil pump cable measurements in
Step 8. It may be helpful to scribe or mark a line
on the end of the lever arm to use as a reference.
See III. 2 and 3.
6. Measure the width of the divider on a metric ruler
to the nearest 1/2 millimeter.
Record this
measurement.
Note: The carburetor slide must be resting against the
idle stop screw and the throttle lever must have free
play before proceeding with Step 7. If you cannot ob-
tain free play at the carburetor even with the throttle
housing adjuster screwed completely into the throttle
housing, loosen the lock nut on top of carburetor, turn
the throttle cable adjuster in until free play is obtained,
tighten the lock nut, and then proceed with Step 7.
7. Place gear selector in neutral and set parking
brake.
8. Start engine.
9. Turn the adjuster on the throttle lever housing
out until the engine RPM just begins to rise.
Repeat this step to make sure you have the
throttle cable set to the exact point where the
slide (engine RPM) just begins to rise.
10. Stop engine.
