Yes, that is what I did today AND previously when I assembled it and installed it, no fuel leaks at all, Just flooding.

Flooding is either a needle and seat issue of a bad float.... Bad brass floats are easy to spot, it'll have gas in it... Nitrophyl check the weight compared to a good float

On the needle & seat, unscrew it from the carb, look for debris in the needle & seat, also check the o ring on the , a tiny nick will cause flooding...
