Walbro list a HDA-87 with a16.66mm Venturi, and a 120 and 144 both with a 15.08mm Venturi. Would a carb from a 268 or 272 work for what you guys are looking for. That should be a Tillotson HS-260A, it has a Venturi of 17.46mm

HS260 has canted mounting screws, HDA is level you would have to make an intake block and linkage problems.
Shep

I supect it is easiest to stay with HDA as well, but believe it should be possible to take the venturi of the 120 and 144 at least out to the same effective diameter as the 87 - provided you know how to do it?
