funny stuff !!!!!! it's usually the little things that bite us.as long as you're tearing it apart disassemble the entire carb and soak it in purple power or simple green for a few hours,rinse it off and blow out every passage with compressed air.before you put it back together spray the bowl gasket with wd-40 so it won't rip if you have to get back in there(and you know you will !!!).let me know the jetting too.
