Re: Lost velocity when going from CO2 to AIR ?
Bleed ALL the air out of the tank, give it 10 minutes, then double check it's empty. You should be able to depress the pin inside the fill nipple with ease when it is. Gauges lie, you must double check with the fill nipple, either by removing it completely or just depressing the pin. Unscrew the top of the bonnet (while pointing it in a safe direction), and remove the cap. Count the shims, and tell us how many and what colors they are.
