Converting my PX125 Lusso to premix. I got this to block the hole from the drive shaft on the clutchside.

That's all fine, but those instructions is not the best. I get that I put the plug with the o rings in the hole, but what the hell am I doing with that tiny rod and the screw? Anybody here have any experience with this item?
