make sure you don't have an extra gasket under the inlet seat. Sometimes the old one stays stuck and looks like part of the carburetor. Look for anything loose in carb ,it don't take much for needle to not seat and resulting flooding.
Being a dual jet it will have a power valve ,make sure that it moves up and down freely. If it don't ,very gently pry it up, it has ,I think a plastic ring that is pressed lightly into the carb body that holds it down. Use something like brillo pad ,grab the one from the kitchen sink while wifey is not watching and polish it up . It won't need much.

The dual jet is good carb ,not real big. I had one for 187,000 miles and no problem.
