1. Variable lever adjustment (1)Fix lever (B) in the beginning of speed increase position using bolts (C) and (D). (2)Fix using the bolt E so that the lever A is aa. (3)Lock using bolt (G). (4)After completing idle adjustment, loosen the full side stopper bolt (D). (5)Move the lever (A) in the full speed direction. (6)Fix bolt (D) at full speed position. (7)Finally, measure the lever angle and set the idle stopper bolt (C) stop position.
