THROTTLE CONTROL ADJUSTMENT
If the throttle control requires adjustment or if it has
been replaced, adjust the throttle control as follows.
1. Remove the screw shown in figure 17. Remove
the cable clamp from the cable.
NOTE: If you have a Tecumseh engine, simply loosen
the screw shown in figure 17A so the cable will move
freely beneath the clamp. It is not necessary to
remove the screw and clamp completely.
2. Push the throttle control lever on the handle all
the way forward as far as it will go, then back it off
one “click”. Make certain the throttle control
lever remains in this position.
Push the control lever on the engine as far toward
the rear of the engine as it will go. Tighten the
screw to secure the cable in this position.
