I need to adjust the guide pulley away from the sprocket on the rear deraileur, but the B screw does not have any more adjustment left. I hope this is an easy fix and I would appreciate any advice on this.
Thanks

Two choices:-
Remove existing screw and fit a longer one.
or - Remove screw, turn it round and fit in the opposite side.
This will put the head of the screw against the frame stop.
A little awkward to adjust but once set it's just left there.

About half way down the page shows what I mean.
Ride hard or ride home alone!
sometimes it can be tricky to install the derailer in just the right spot on the hanger, i'd check that first, and make sure the hanger isnt bent. did the bike recently fallover or crash? are you installing a new derailer? maybe you just got the bike and dont know its history? just tryin to help.
Get on your bad pedalscooter and ride!
