QUESTION: No i didn't blow it out, that was my next step unless you had another idea.

Answer
I would remove, dis-assemble and blow out all the carb orfices with compressed air from an air compressor.  Make sure the blow out the small holes in the carburetor throat.

TIP:  Take lots of digital pictures before and during removal so you know how to re-install the carb and connect the linkages.  Marking the connecting links will also make re-assembly easier.

Do you have the Briggs or Kawasaki engine?
