We use the Toro 22040 with the two stroke Suz. engine. I am looking for a second and of course a less expensive source for the the carb shafts, throttle valve(plate), ring and seal for the Minkuni carb (906D0). If anyone has info on this or the original Mikuni part numbers I sure would appreciate a heads up. Every year I have a hard time coming back from the dealer with a small handful of parts that represent over 25% of a new carb.
