Not all of the 650s are being recalled. The ones with a small bump next to the flow adjustment are the ones being recalled (check SP website for a better description). I just had mine replaced. They sent a prepaid return box to pick up my 1st and 2nd stage. They gave me a completely new 650 with a new serial number and inspected the 1st stage. It was gone about ten days and they say you still need to do your annual on it. Good luck.
