Welcome fellow Somerset-based newby, but apologies that I don't know the answer you seek... someone on here will help you soon!

Cheers, D.

I don't know that specific carb but the general rule for 90% of carbs is a screw at the engine side controls fuel, one at the filter side controls air.
So engine side out is richer, filter side out is leaner.
