[Mgs] 74 B stalls on right hand corners

What does the tach do?  If that continues to register while the engine is
turning from the forward motion of the car then it probably is fuel but could
be HT.  If the tach is dropping to zero when it happens then it is ignition
LT, quite possible that a poor connection is breaking or possibly shorting on
the one bend.  Check the distributor cap, rotor, HT leads and plug caps for
condition and security in case it is HT.

Because the float chambers are presumably full I wouldn't expect an instant
response of stumbling and stalling as soon as you make the turn certainly not
from fuel starvation, and probably not from flooding, although the restart
requirements do indicate flooding which is normally accompanied by a strong
fuel smell.  It's possible debris in the float chamber is moving around and
blocking something on right-hand bends, although I would expect that to affect
HSs more than HIFs, and only one carb, same as flooding.  Grose jets used to
be recommended, but current wisdom is that the quality and performance of
those has deteriorated whilst the viton-tipped standard valves have improved
and are now much better.

A 74 should have the anti-runon valve and again a wiring problem could be
causing that to operate when it shouldn't.

  Subject line tells the story. Take a right hand corner at more than a
  walking pace and the car will stumble, stumble, stumble, and stall in a few
  seconds.
