ADJUSTING THE SPEED SELECTOR
If the snowthrower is slow, the No.1 speed selection has no speed, or the speed selector does not move into the No. 3 speed selection, adjust the speed selector linkage.
1.Disconnect the wire from the spark plug and make sure that the wire does not contact the spark plug.
2.Tip the snowthrower forward and block it so that it cannot fall.
3.Remove the four screws that secure the bottom cover to the frame and remove the cover.
4.Loosen the flange nuts that secure the selector plate to the control panel (Figure 65).

Note: The drive assembly should be 1/8 inch (3mm) from the roll pin; if not, slide the selector plate (Figure 65) until the gap is 1/8 inch (3mm) (Figure 66).
