34. 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 con-
trol 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.
