All I can see on the 2 cylinder motor is that the top carb might be a little closer to us then the bottom; but then maybe not, maybe it is just the float bowl position. I agree there doesn't look like enough space behind the carbs for a regular disk feeding 2 holes ... suppose it only feeds one hole and is only cutting off some piston port timing on the wrong side of center?
I think I know what that plate with the 4 holes is ... a dual rotor plate to allow 4 carbs like the piston port VC. Maybe it was the prototype before the single rotor 2 carb design was decided on.
Looks like there may be a rotor for it hanging on the nail behind it.
