Small update on the carb mounting. When I tried to fit the nearside carb it still fouled the chassis - doh.
So I bit the bullet and modified the inlet stubs adding a new bit made from 1 3/8" ally tube which just happens to be a good match. (No it's not my welding....)

The only downsoide is that I used about 50mm of the ally tube - but I had to buy 2500mm! Perhaps I'll go into production...
