Back to the original issue of the carburator if I may. I too am also looking at mine which by the pictures from Highflyer, looks exactly the same. Also "No Tag". Numbers seen on the Carb are YF, 1-630, 0-824, 6-723. My research also led no where. I would like to know exactly what this carb model is to possible order a kit, and also know what yrs. this was used on. Thanks, Tom
