true im not ruling anything out just yet, but earlier today i was tinkering with some other valves an noticed something about them. On the right side of the valve (looking at it bolted to the frame) where the 2 fittings are for the front wheels, there is a rubber cap an i guess you call it a button. While i was tearing the other valves apart, i noticed that each of the ones i tore apart that button was froze an knocked two of them loose. with that being said, if that button is froze would that cause that valve to to work right? just thinking?
