1.
Hold the (cast) inner throttle lever in high idle
position. Move the outer (sheet metal) throttle
lever to the 5.20"/5.68" dimension for Version "I"
(Figure 4a) or 5.20"/5.45" dimension for Version
"II" (Figure 4b). Use a ruler to measure the
gauge dimension.
2.
Change the mounting position of the lever on the
throttle shaft until gauge dimension is obtained.
3.
Tighten bolts as specified in Figure 4c.
IMPORTANT

9.
This procedure should result in pump lever over-
travel of one half the available movement (8° +
1°) when the accelerator pedal is pressed to the
floor. If this does not result from the first
adjustment repeat procedure until the proper
override is accomplished.
