filling like that works ok on the later holly/Ford carb but not on the early one ,The doesn't seem to be a issue on some others makes such as Chevs because the pumps is low on the moter. AS a Boy we to poured gas down the carb like you , we worked 700 milels away from home .To re leave boredom we worked on our fords at night with a lead light out the window of our quarters .These were cars we picked up of Farms .One time I was worked the starter while my dear dad poured Gas down the carb ,and it spat back and blew gas all over him ,on fire he ran down the car park slapping his back, it went out ,All I could do was laugh it was the funniest thing to see .
