Too much pressure??

I took the carb apart again & discovered the little inverted "U"shaped spring that holds the float where it pivots was hanging up on the float in mid-range whenever gas was introduced into the bowl. I messed with it some & put the "U"shaped spring back so the float now moves freely. I even had some fun testing it to see if my repair would cure the problem. I was smoking a cigar & blew smoke into the fuel line with the empty carb right side up (float at the bottom of the bowl) & smoke flowed freely into the carb & out the little bowl vent. Then I did the same thing, gradually turning the carb upside down while again slowly blowing smoke & I could feel the smoke flowing less until it was blocked completely when the float reached the top of the bowl. I'm easily amused.
The carb works great now & no leak anywhere. Thanks for all of your help!
