tion Agency) regulations which require exhaust emission con-
trol. As a result, the carburetor adjustment needle(s) are
equipped with plastic cap(s) that limit the rotation from the
original factory adjustment. If your unit exhibits specific perfor-
mance problem(s) where the Trouble Shooting Section recom-
mends a needle adjustment and you are at the limit of adjust-
ment, the unit should be taken to a factory authorized service
dealer for repair.
