pulley. See Fig. 7-3.
2. Route the end of the belt around the auger pulley and slide
the pulley back on to the auger shaft. It may be necessary
to push down on the idler pulley to get the auger pulley
under the belt keeper.
3. Replace the flange nut and tighten securely.
4. Reinstall the belt cover removed earlier.
5. Remove the board from the auger and chute.
6. Tip the snow thrower back to the operating position and pull
the starter handle a few times to see if it is difficult to pull.
7. If the starter is difficult to pull, remove the spark plug and
pull the handle several times to ensure that any oil trapped
in the head is removed.

re-installing.
