If you operate the pump with the Presta setting, but not connected to
valve, does it register any pressure on the gauge? Compare this to
Shraeder setting. Is there a difference? On the Presta setting can
compress air, so you have a gauge reading that does not bleed off?
be that there is a scrap of rubber in the valve that is blocking air
I think I will give some advice on this one....ummmmm......maybe not.
