There must be some very minor difference, but I don't know what. It's not the vacuum valve. And I think the jetting is the same. I've rebuilt sets of both numbers and could see no difference. I'd use the ones original to the bike just because, I guess.

The needles and the seats on the VB61 carbs are different from the VB60s and the original VB61s on my German 79 did not have the stop covers over the mixture adjusters.

Mike,

In what way are the needle / seats different? I haven't noticed any differences with them on VB60's vs. VB61's. I have seen US models that have the mixture screw "disabled", whereas Euro models don't have that. I haven't noticed any other differences internally.

Paul: I cannot tell you what exactly the difference is, I just know that the sets have different part numbers which applies to both needles and seats. The original Honda replacements I have listed for my carbs show that. I would assume it is the needle and seat shape.

OK, but in my parts book (April 1978 version), none of the internal parts / linkages have region specific part numbers. Only the carb bodies (complete), and the full rack of carbs have different codes.

Anyway, doesnt really matter.

Both sets of VB61's have vacuum fuel cut outs fitted but the VB60's don't. is this the only difference?
I'm interested in buying your seized carbs for spares Tripnut, I'm near Gatwick 07971 169980.
