Adjustment

1.Lock the ground speed control lever in the neutral position.

2.Measure the length of the neutral return spring (C, Figure 29) it should be set at 3.25” (8,23cm). If the spring does not measure 3.25” (8,23cm) loosen the front set collar (D) and the rear set collar (A), then move the front set collar forward or back on the neutral return rod (B) until the spring length equals 3.25” (8,23cm). Retighten the front set collar.

3.Make sure that the neutral return bushing (E) is seated correctly in the spring stop plate (F).

4.Position the rear set collar so that it sets tightly against neutral return bushing and tighten.

5.Pull the ground speed control lever rearward and release to check position again. Adjust as necessary to align the ground speed control levers with the notches in the neutral lock plate.

It is important to note that after every adjustment of the neutral return rod, the lever must be pulled rearward and released to properly check the neutral position.
