Booster Spring
- With idle speed correctly set, move speed control lever to idle position. Loosen booster spring retaining nut on speed control lever. Loosen lock nuts on eye bolt at opposite end of spring. Move spring retaining bolt in slot of speed control lever until center of bolt is on or slightly over center (toward idle speed position) of an imaginary line through bolt, lever shaft and eye bolt. Hold bolt and tighten lock nut.
- Start engine and move speed control lever to maximum speed position and release it. Lever should return to idle speed position. If it does not, reduce booster spring tension. If it does, continue to increase spring tension until it does not return to idle, then reduce spring tension until it just returns to idle. Tighten lock nuts.
