Re: Lost velocity when going from CO2 to AIR ?
If you bought it from a local store, I would take your marker and tank into them and tell them the tank is not working with the marker, and see if they can help you. Emptying and messing around with the different parts of the tank regulator is not to be taken lightly and is not for beginners. Doing something wrong could seriously injure you or someone else around you, as well as damage the tank rendering it useless. If you are new to the sport and don't know much about the tank, I wouldn't take it apart by yourself.
