VHB27 on a Narrowcase 250

[amartina75]

Is anyone running a VHB27 on a NC 250? I am wondering what setup to use. I have a 250GT motor on my 66 Scrambler and I'm currently using a SSI27D carb on it.
I have a VHB27 in good shape but it is off of an Aermacchi. I would like to put it on my 250, i think it would probly run a lot better with it. The Tech Section doesn't
show that any Ducati ever came with a VHB27 installed, which really doesn't make sence, it seems like it would be a perfect carb for a widecase 250.
It shows that a widwcase 250 with a VHB29 would have:
V13-needle
110-main
40-idle jet
40-slide
265m-needle jet

A 250 widecase with a VHB26BD would have:
E-17 needle
95 main
45 idle jet
40 slide
260R needle jet

Can anyone recomend what I shoud use?
Thanks,
Aaron
