My next question is: Has anyone ever tried angle drilling the extra passage into the carburetor throat for the pilot circuit.? I believe it's mentioned on the 490 molding article.                                                     
BTW, none of my carbs has a replaceable air orifice into the pilot circuit at the carbs bell? Is this not on U.S. models?
