XR50 with 88cc Big Bore kit (Throttle Sticking open)

Hi All,


I just bought a 2003 XR50 for $200.00, it has an 88cc Big Bore kit & aftermarket bars and throttle assembly. After cleaning the carb I noticed that the little rubber needle for the float was cracked. Could that be the reason that the throttle sticks? The cable seems like it is free so not ruleing that out, just figured a noticably worn part was suspect as well.


Side question, how to I fgure out what needle I need to get for that carb, even though it's aftermarket are parts likely standard for the 88cc kit?
