1. 0.3 mm (.012 in) gap maximum

NOTE:

If there is no gap between tab and plung-

er, a rich condition will occur and throttle response
will be affected; if the gap is too great, the plunger
stroke will be reduced causing poor cold engine
starting.

If adjustment is required, loosen cable support on
middle carburetor to change choke cable position.

1. Choke cable support

After adjustment, retighten screw.
