Float level too high. Wrong jets.

Bill,

Did you read the original post? The guy replaced the carb with new. Very
doubtful the carb was the problem in the first place. Guy probably wasted
his time and $$$ by replacing the carb, right?

Yes I read the post about new carb. And I have had stuck float in a newly
rebuilt carb, and the new carb could be jetted for a different engine. The
choke could be stuck or adjusted partially closed.
