Well, the throttle cam pick up adjustment won’t affect the position of the roller on this engine, the cam moves in and out to set the pick up.
Again, I don’t think those wires are properly routed/clamped into the mag plate, which is why the roller seems to be hitting the wires and perhaps opening the butterfly a bit when the throttle is all the way retarded/in the stop position.
