That would be nice if you could try out someone else's larger carb. You know the size differential is up there in the higher RPMs (not down where you're having the problem) -- but it's only a few hundred bucks either way, and you can always recoup a good bit of that regardless (and ERA Chas drops that kind of dough just on dinner), so I say "roll the dice" and see if the bigger carb fixes you up.
