shown in Figure 15. Reassemble, placing the bottom holes in the handle over the weld pins in the handle mounting bracket.

Reassemble the upper handle.

Place the hairpin clips in the inner holes in the weld pins and attach the starter rope as instructed in the Set-Up Instructions.

Throttle Control

If your lawn mower engine is equipped with a throttle control that needs adjustment or if it has been replaced, proceed as follows. Note that engines with fixed throttle cannot be adjusted. Three types of engines are illustrated in Figure 16. Follow the illustration that is applicable to your mower.

Remove the screw that secures the cable clamp. Remove the cable clamp from the cable.

NOTE: If you have a Tecumseh engine, simply loosen the screw shown in Figure 16 so the cable will move freely beneath the clamp. It is not necessary to remove the screw and clamp completely.

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. Secure the cable in this position with the cable clamp and screw.

Carburetor

WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and muffler.

Minor carburetor adjustments may be required to compensate for differences in fuel, temperature, altitude and load. To adjust carburetor, refer to the separate 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.
