any carb can be made to supply a heck of a lot of fuel...u can easily double the jet size which will supply way too much fuel...and if the jet aint big enough then drill it...so fuel isnt really a problem as much as airflow...but your right about the draw through and pressurize...the draw through needs to be bigger for sure as the air is atmospheric like u said and its being sucked...a smaller flowing carb would work fine as most of us use carbs that are too small anyways (stock setup) also i dont think u need as much fuel for less flowing carbs as with higher flowing carbs...at least thats what i find with naturally aspirated engines...although with forced induction extra fuel is needed anyways...hmmm
