    maybe I see things.. why is there hose on the pulse nipple behind the carb    ?   hopefully is it plugged further down… if not you would loose crankcase pressure to drive the small square pump.      Just cut that hose and plug in a short bolt.

    hopefully the  small square pump’s rear pulse port is directly in line with the pulsing hole you drilled in the bypass cover plate otherwise the pump won’t work to suck  fuel and refill the carb  forcing you to repump the bulb to fill the carb. .

    btw  don’t overrev in a bucket …aerated water won’t cool the engine much   just idle it.
