This leads me to believe that you have a too high of a float setting.
I don't know what kind of carb you are talking about, but as rule of thumb, I set float heights to 1/8 inch or 2mm below the gasket surface when I am repairing a mystery carb.
it is this style carb
I had an nt on it and just bought this for cheapness
