Could be as simple as moving the fuel lines to the carbs if they are too close to the heads or engine block. If they heat up this could be the cause of vapor lock. Moving 1/2 inch could cure the problem. Have heard of gasket between a carb and engine is too thin and a carb heats up and causes a vapor lock. Also Check fuel lines for kinks. Also check that the fuel line and primer ball don't have a very small crack as this will cause too much air and no fuel. Check the simple things first.
