Backstory here…..
Loaned my gauge to a friend. It wasn’t working so I had him check to see if the valve was messed up, and it was. Spring was all jacked up.
He put a valve in it from a bicycle and tried again. Wouldn’t read over 80 PSI. So he bought his own and had compression on that gauge in the 125 range.
I figure I will buy the compression gauge-specific Schrader and see what happens.
