I kept fiddling with it until it finally went. I then went to LBS and bought CO2 setup. Screw frame pumps when it is below freezing.
Wait until you try the co2 below freezing !!
Ever see then ice up when you use them in 90 degree weather? The nozzle freezes in the cold. The only way to get much out of it is to put the cartridge in the inflator and put the whole thing under your jacket until it is nice and warm. Then attach it and use it quickly before it cools off too much. You still don't get much pressure in the cold as the temperature changes what pressure you get in the tire. Don't count on the co2 in the cold.
By the way, you can warm up the head of your frame pump by puting it in your jacket too, then it works.
Alkaline powered lights too, in the jacket. Water bottles too.
