Sam,
Before you start changin' jets, you may want to dip the carb body.
My '01 spent a summer in a tool shed in Houston before I bought it. The carb was all gummed up. The carb body itself has some small caliber plumbing that is impossible to clean correctly using mechanical means.
I bought a gallon of Berryman Chem-Dip at Autozone.

Worked for me!
Good luck!
