Tomorrow I am going to get the twin carbies right.
For some reason the front carby hisses much louder than the
rear carby, even when the throttle screw is wound right out.
The throat of this carby has a wear groove where the butterfly rests.
Would this be the problem?
I have a choice of 4 replacement bodies, what should I check for?

That's probably the problem.
Check for wear there on the bodies, and in the throttle spindle holes.

Just check that the choke lever isn`t resting on the "High Idle" screw first.

Thanks MiniMan for the reminder, I had wound it out too.

I took the carbies off and upon closely examining them, the front carby had this groove at the top of the throat where the butterfly seated but the needle was slightly worn at the top for about 3mil along it's length.....it was shiny, so obviously the jet was not centered....so I figured the jet would be also worn on this carby......so I swapped the front carby slide and bell into the rear body and vise versa......and it worked quite well......not perfect but much better.....the needles did not bind, but next weekend I'll centre the jets just to be sure.
