Butterfly Throttle Plate Numbers - Significance?

[Mr.humbucker]

I've searched on the forums for an answer to this one but couldn't find one.

I am rebuilding a set of carbs for a GS550. Two of the bodies had issues that require me to replace them. The original set had 140 stamped on the brass throttle butterfly plates. The set I picked up to use as replacement bodies have 130 stamped on the plates. I've measured them and see no difference. Can anyone out there in GS knowledgeland tell me if there is a difference?

Do a good bench sync since the butterflies have a different angle. The different number on the butterfly will have a different adjustment on the set screw.
Get them lined up and you are golden.

Thanks very much - I appreciate the information!
