Well I’m back and since the change to Mortons it would appear that anything anyone had posted in the past has been consigned to the bin. Consequently I missed this question
I used and commercial carburetor from Hobby King, that was probably one of their OS engines copies which they don’t appear to do these days (I wonder why?). I’ve had a look at the OS engines site and can’t find any carbs there either.
I’ll have a dig around and see if I can find any further clues
