<VV> S U Carb to replace YH

[Nick R]

Hi

I am looking for any tech articles or direction that should help me learn
the best way to set up a 2" S. U. Carb to replace the stock YH carb on my
150 hp turbo. The SU looks to be complete, other than missing the needle
out of the center slide. I'm looking for which slide needle should be a
good size to start tuning the carb in with. I don't mind doing the
research, except I am not finding any written information so far in my
search.

Thanks, Nick
