Yes a fuel pressure gauge t into the fuel pipe just before the carb. It should hold a steady pressure if it jumps about it I struggling to keep up with your engine. Also some pressure regulators come with gauges which would be even better. It can flow with an open pipe ( squirt) but doesn't mean you have correct working pressure when it's connected in. Carbs are sensitive to pressure. If you don't you could be playing with your carb for years and you will never get it right. Interesting post this one!
