I got these a while back and never looked too closely at them.
They are supposed to be for an MC16 and they are 28mm bore.
They do not have the fittings for the oil pump hoses, nor have they ever been drilled for them.
The throttle bellcrank also has no provision for an oil pump cable and the throttle cables enter from the rear. The fuel hose "tee fitting" exits between the carbs rather than the right side of the right carb.
The carbs on the right are "normal" MC16 carbs for reference.
Anyone have any ideas ?

I can tell you what they're not... they're not the same as my HRC carbs.

I think they are NS250 carbs. Looking at the way the cables attach, it looks like the carbs when fitted, face forwards... same as on the NS400.

I'll go with ns250 carbs, if I remember rightly the oil feeds to the inlet manifolds on that model. I can look at my mates one if needed..
