Well, if not "turn cutout" - which is pretty normal without mods to the
carbs - on a tight (especially accelerating) turn, it could be a matter of
carb sync or a matter of distributor advance not coming in soon enough. I'm
a bit perplexed since you seemed to indicate that it only occurs or right
hand turns. The floats are not set properly (equally) on both sides? It
could also be a matter of the secondaries not "coming in" soon enough (and
not matched well with the timing advance [or not]). Just HOW LOW is the
fuel in the tank? I doubt it is related to the E fuel pump. But, I suppose
that it could be related to slosh in the tank (that's a guess).
Start by filling the tank (with 93 or better octane) and let us know if
there is a difference. We can take it one step at a time.
