As The Good Dr is always out of stock on carby kits , I tried Out West Motorcycles and Lo ! they had several different versions of the Kyster kits for the square bowl carby IN STOCK @ $23 so I bought one of each as most of my Hinda 90's have this carby ~ these kits come with all rubber parts , jets , float needles , the two tiny springs for the adjuster screws and so on... Best of all ~ 48 hours shipping . wow , such a deal .
