TO ADJUST THROTTLE CONTROL CABLE (See Fig. 31)

The throttle control has been preset at the factory and adjustment should not be necessary. Check adjustment as described below before loosening cable. If adjustment is necessary, proceed as follows:

With engine not running, move throttle control lever from slow to choke position. Slowly move lever from choke to fast position.

Check to see if hole in throttle lever and hole in speed control bracket are aligned.

If holes are not aligned, loosen cable clamp screw and align the holes by inserting a pencil or a 1/4" drill bit through both holes.

Pull throttle cable up to remove slack and tighten cable clamp screw. Remove alignment pencil or drill bit.
