The blowback operation of the Stingray is fascilitated by loose tolerances of the valve stem/powertube inside the bore of the valve nut, right?
So how do we eliminate said blowback, whilst still allowing free movement of the stem/powertube?
My first thought is to groove the @$$-end of the valve stem/powertube for an O-ring... but I lack a lathe, or even a drill to chuck it in... got some files, though.
I am not opposed to sending a stem/powertube to someone with the proper tools.
However, I wondering if it would be better to groove the inside of the bore through the valve nut...?
Is there any practical difference between putting a dynamic O-ring on the stem, versus a static O-ring in the valve nut?
