<VV> Strange Performance Flat Spot

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.
