The setting controls when the valve closes relative to float hight (and
therefore fuel level in the float), so it is the same no matter what type
of valve you use.
The TD/TF Workshop Manual (the factory book) specifies 3/8 inch (9.5 mm),
which I have always used. Various aftermarket manuals list 5/16 inch or
7/16 inch, which are appropriate for some other SU applications, but I've
always gotten the best results from 3/8 inch with the H2 and H4 carbs used
on the TC/TD/TF.
Others swear by 7/16 inch (11 mm). I'd suggest that you try 3/8 inch
first. If that doesn't give good results, try 7/16 inch.
