THROTTLE CONTROL ADJUSTMENT
If the throttle control requires adjustment or if it has
been replaced, adjust as follows.
1. Remove the screw shown in figure 19. Remove
the cable clamp from the cable.
NOTE: If you have a Tecumseh engine, simply loosen
the screw shown in figure 19B 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.
3. Push the control lever on the engine as far toward
the rear of the engine as it will go. Secure the
cable in this position with the cable clamp and
screw.

Minor carburetor adjustments may be required to
compensate for differences in fuel, temperature, alti­
tude and load. To adjust carburetor, refer to the sepa­
rate engine manual packed with your mower.
NOTE: A dirty air cleaner will cause an engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor. Refer to
