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.

ment should not be necessary. However, minor adjustment
