I have sat with this engine in the garage for a while now.  Family, work, house, and an MA all got in the way.

2332cc
42 x 37 CB wedgeports
56cc chambers
raptor cam (don't know lift)

I need to do a cam burn and get it up and running so want a conservative jetting arrangement that will fire up and not lean out.

I have 37 and 40mm venturis.

As far as I can tell they have 135 F7 120 in already.  With idles saying 70F10.

Thanks in advance, this is the last piece of the jigsaw.

To do cam burn its only going to be on idle circuit so you only really need to worry about that, 70s will be fine and use either vents, if you want a ball park mains then 170s with 200 airs
