Reposition the right side pulley in the slot and tighten. Recheck alignment of the bolt on the spring loaded idler. Figure 4 THROTTLE LEVER TENSION: 1. If throttle lever becomes loose, tension may be adjusted by tightening the pivot bolt. The pivot bolt holds the throttle arm to the throttle mounting bracket which is located under the console. Access is gained by removing the foot plate and the kick plate. Rotate seat latches out to release seat. Put seat in rear slide position, tilt seat forward, remove seat stop rod bolt and nut, tilt seat forward to rest on front frame. Start with either the right or left motion control lever. Move the motion control lever to the neutral position then pull the lever back until the clevis pin (on the arm below the pivot shaft) comes into contact with the end of the slot. At this point slight spring pressure should be felt ( See Fig 5a). Check where motion control lever is relative to the neutral slot in the console. The lever should be centered to allow it to pivot outward into the neutral slot. If adjustment is necessary, loosen the nut against the yoke. Apply slight rearward pressure to the motion control lever and turn the head of the adjustment bolt in the proper direction until the lever is centered in the neutral slot. NOTE: if properly adjusted the motion control levers will return to neutral from the reverse position and reverse motion will stop if levers are released.
