The problem seemed to be lack of fuel and no accelerator pump squirt on two of them. There is an inline electric pump at 3-4 lbs. Upon removing the tops, it was discovered that the two driver side carbs did not have enough fuel to reach the slot in the accelerator pump cavity (thus no squirt), but that the passenger side carbs were full. Had to be a plugged line, but found nothing wrong. A little trash in all of them but nothing to write home about. Venturies are dirty, indicating backfiring. Really want to try determine what is wrong before re-rebuilding them. No gremlins found.

Could some bit of trash have found its way into the fuel pump and then 
wedged itself into the fuel outlet T-fitting leg that feeds the 
offending carbs... maybe?   Not a lot left to suspect at this point.
