I need to purchase a carb kit for my Troy Bilt leaf blower, Model TB250B. It is a 2 cycle, 25 cc engine. There is nothing on the carb except W1732 631. NO NAME. The Troy Bilt parts list shows the carb number is 752-04584 but I just need a kit. Does anyone know what carb is on this blower? Randy's small engine parts was no help at all.
