adjustment in cable tension. To adjust, disconnect the
end of control cable from the bottom hole in the control
handle and reinsert it in the upper hole. Refer to Figure

difference.
If additional adjustment is required, proceed as follows.

snow thrower's auger housing by unthreading the
five hex screws which secure it in place. See Figure

moving the clutch cable spring. See Figure 9.
