I'll have to use a bellcrank of some kind. Don't know where yet, until I get my mounts.
I would have liked to open the adapter up, but as you notice on the case, it has a rectangular hole. If I was to open to the full diameter as the carb, it would cut into my pulse hole, and that just wouldn't work. It's about as wide as I dare go.
if you decide to make a new adapter out of epoxy board you can rotate the carb to any position you like. lop off that little nipple, drill the adapter to match the cylinder pulse hole, position the carb where you want it (needles to the rear, straight shot linkage) and mark the spot where the carb's pulse hole come out. now use a dremel to route a channel that connects this spot to the pulse hole you drilled. keep this channel about 2mm away from the big hole in the adapter and the carb gasket will cover it right up.
getting rid of that nipple will also allow you to enlarge and match the adapter to the carb throat.
should be a link here for the G10 epoxy but can't find it.
seems i also remember someone buying a big chunk and offering small pieces to those who needed.
Mike, the walbros of mine have a "ready to drill" spot on the pump cover for the pulse line. my small zamas look like they have this spot cast into the body itself.
