How about an overfull float chamber caused by leaking needle valve?  Dumps
the extra gas into the throat on the tilt up plus acceleration.

I know fuel starvation is the popular line (and I expect that's what it is),
but hey, why not be different?  When mine didn't pick up from running slowly
I assumed a weak mixture, but a CO test showed it was too rich, and a
mixture screw adjustment (or two) did the trick.

OTOH the channel by the main jet could hold a lot of muck (or even a small
piece) and be enough to temporarily block the jet.  The balance pipes can
help out surprisingly well at higher rpm.
