Seems to be a disconnect regarding JTS Warranty Service. They've quickly, without question or charge, shipped needed parts to me while others have been required to return for repairs. Possible were dealing with different entities such as Dealer Warranty Centers, as well as JTS Warranty Center. Also, possible JTS has had a change in policy regarding warranty parts and repairs. Difficult to say, at least there's a response to consumer problems. WM
Grouch-O posted a thread, "Modding a M60B (.35cal) ..." yesterday which included a picture of the valve system. Appears Snowpeak also included a washer between spring and plastic so maybe there's something to it. WM
Just found in washer collection can, needs to fit somewhat snug over 3.85mm (.15") plastic tab and at least .317" diameter to cover where spring sits. Larger than .317 is OK, you can see mine overhangs a little in photo. Used SS for corrosion resistance but smear of silicone grease on non-SS would work. Thickness of washer shouldn't matter. WM
Remember the spring narrows down and snug fits on that 3.85mm wide tab so sharp tip, that digs into plastic, will be close to tab, that's why snug fitting washer is important. Don't think washer is rare, found a number of them easily in can. WM
