If you have access to a lathe, you might be able to turn down one for an OS15 or 25.  Then use nylon spacer blocks to center the spray bar holes in the venturi.

If you can't fit the threaded part of the spraybar in the crank case holes then you're already shot out of the water, unless you want to hack up your crank case.  But if you have a spraybar where the threaded portion will fit but not the smooth portion, it should be reasonable to turn it down.

The carb retaining screw in the parts list is M3 so the NVA from the 15 should fit.
