    I don’t think the crankcase pressure pulses can possibly over pressurize the tank.  Tillotson did make a number of different float needle & seats.  Maybe (???) it has the wrong one installed.  Too big a seat diameter could result in pressure forcing it open.

    I’m somewhat surprised that it is running with the carb overflowing like that.
