It's been so long I forgot which car you guys are talking about, but no way
there should be any back pressure in the float chambers with no fuel in the
line. The float chambers are supposed to be vented when the engine is
running. ALWAYS! Just pull the vent hose off of the carb vloat chamber(s)
and see if your problem goes away. If that works, then look for the reason
it's not venting the float chambers.
I seem to recall that Carl said '67 MGB. If that has the original carbs
the vent lines should just drop down by the side of the engine and be
permanently open vented to atmosphere. Hard to believe that both would be
plugged, unless some DPO was up to no good.
