Peek down the intake with the throttle open. describe what you see of the top of the brass outlet where the needle slides in and out.
Does the carb have an scree adjuster for the slide, for an idle throttle opening? (There are versions- smoothbores -that don't).
I go with the 'assume nothing' view - e.g. 36mm Mikunis will give the same power as a 38 on a GS, though the mid-range is allegedly better.
