I'm scratching my head about this one, too, but don't think it would be a matter of too much fuel. Generally, popping back through the carburetors is a matter of leanness, timing being off, or a bad intake valve allowing the normal combustion process to fire jets of flame back into the intake manifold. Since more than one set of carburetors have been used, it kind of eliminates anything like float levels or such. I'm thinking more along the lines of leanness or such. Is there a possibility of one of the large diameter vacuum lines having a crack that opens up from centrifigal force during a turn? I had a car with a cracked flexible fuel line that ran wonderfully all the time except when you gave hard throttle away from a light. It'd get up to about 35 mph and die. If I kept my foot on the gas it'd start to run strong again and then pass out, repeating the cycle over and over again. It was the torque from the engine tipping that opened and closed the leak. Took about a week to figure that one out! This is just more grist for the mill... and I am sure you'll let us all know what was the problem. Good Luck!
