Jetting is a process with Webers, you could try different sizes, but I don't like mixing them up. I went up a size and turned down the mixture, that worked for me, I think I run 55 or 60's, my Webers came with 50 if memory serves.....every cylinder is an individual and has to be tuned accordingly.
best of luck,
Chas.
