what i will be doing to keep the float chamber topped up is one of a few things.
either boost operated solenoid with a 1mm jet to feed fuel into the carb base.
or, my favourite... just use a grainger valve/ dawes device (although you would have to solder up the small hole they seem to have), set the open pressure to be about 20 psi, which would correspond with about 15-16psi of boost + 4psi fuel pressure. the ball internally doesn't allow fuel to flow backwards, its fairly cheap, and mechanical (so less to go wrong...)
this way you dont need to worry about large needle jets etc etc.
