Bennie, it sounds like the float level could be low, leaning out the mixture.
If it were a sinking float with a leak in it, the needle & seat would be open too much of the time, high level fuel flooding over into the venturi. Some times you can see drips of fuel while at idle. This sounds like a gurgling while at cruise.
If it were a brass float, leaks can be found by putting it in a pan of boiling water & watch for bubbles escaping.
