Booster
With the idle speed set, adjust the booster spring
spring
as follows:
a. Refer to and loosen the booster spring retaining nut (41) on the speed
control lever (40). Loosen lock nuts (21) on the eye bolt (37) at the
opposite end of the spring (22).
b. With the speed control lever in the idle position, move the bolt in the slot
of the speed control lever until the center of the bolt is on an imaginary
line through the center of the bolt, lever shaft, and eye bolt. Hold the bolt
and tighten the lock nut.
c. Start the engine and move the speed control lever to the maximum speed
position and release. The speed control lever should return to the idle
position. If it does not, reduce the booster spring tension; if it does,
continue to increase the spring tension until the point is reached that will
not return to idle. Then, reduce the tension until it does return to idle and
tighten the lock nut on the eye bolt. This setting will result in the minimum
force required to operate the speed control lever.
