Presta Valve issue (inflating problems)
For some reason it is extremely difficult for me to pump up my tires with the presta valves. The air will not go in unless I push the pump so that it's at a slight angle to the actual valve. This damages the valve though (bends it) but has been the only way to get the air to go in at all. So what's the trick....I'm obviously misisng something obvious. But no matter how far onto the valve stem (or not far) I attach the pump the air will not go in unless it's at an odd angle that bends the valve "pin" or whatever it is.

After you gave me the make and model of your pump, and I saw that it was similiar to the mini one that is on my bike for those tire emergencies, I used it to pump up my tires (don't usually use it a lot). But I did notice that the attachment on the pump that is pushed on to the Presta is skewed at about 15 degrees from being perpendicular.
So if the valve is at the 12 o'clock position on the tire, the pump housing will actually be pointing towards the ground. If the housing was perpendicular to the Presta valve, I can see where I could bend it when pumping. But with the housing skewed like it is, I am actually pumping up towards the valve and not pushing on it.
Does this describe how yours works?
