On my IO360 with factory injection on Superior cold-air forward facing sump and cross-over exhaust, my throttle arm that the control cable connects to has a 1" offset from the castellated portion where it connects to the throttle body. That 1" offset just barely contacts my exhaust pipe and obviously is too close to allow attaching the throttle cable. I need a 1/2" offset or even a straight lever arm with zero offset. Where are these available?
