I did the clear tube test from the overflow nipple up and the fuel level is to high. Is there any other way fuel could pass the needle and seat and flood the carb?
good on you for checking fuel level with a clear tube.
here are a few things to verify.
your float height setting is wrong, your technique for checking it is wrong, or both.
float installed upside down, or its hanging up on its pin.
if your fuel level is too high, your float/float valve are not working as they should.
