i would just end it and get a carb rebuild kit i ordered one from this place powersportsstore.com and it was pretty cheap. you prolly cant go wrong with rebuilding it with new parts and what not.
sounds like you need a rebuilt kit. i got one from this place powersportsstore.com and it only cost me like 22 bucks. then i just rebuilt the carb and was good to go.
I always order my tires from powersportsstore.com If you call them they can order you pretty much order you what ever you want. the guy who handles the orders over the phone was cool too.
