It should be a set screw. You should be able to rotate it any way you need.

I'm trying to make sure the throttle linkage on my 8ight is as straight as possible. Doing so would mean my adjusting (turning) the ball on my carb clockwise about 1/4 turn. How would I go about doing this???? I see a hole on the opposite side of the ball, but it looks more like a rivot than a hex screw. Any help would be appreciated. Thanks!
