You mean the idle speed doesn't change when you lift the air valve about 1/8 inch ?
The smarta$$ in me would say that you have the mixture perfect.
But, I have to go back and say this about that as a recent occurrence. The mixture will not change on it's own and by changing the annular space between the metering needle and the jet isn't going to do anything about the gas smell.
On the other hand, the needle valve which in conjunction with the floats controls the flow of gas into the float chamber can foul up pretty much on it's own.
Debris from the fuel line, and "varnish" left behind from evaporated gasoline during storage will make the needle valve stick resulting in either too much or too little gas for the carb to use.
That, and a deterioated diaphram are about the only things that can chance over time without human interference.
