Hi - I am not sure exactly what year my sons 50cc husqvarna is because the bike was powder coated over the vin, it does not have a radiator if that helps determine yr, it is a 50cc. The metal threaded tube that comes out of the top of the carb is broken & I´m trying to find a replacement - any suggestions. I got the motor# but that is all. FMS5*04403 P
