Boy...the tank works with every other gun I have. How could the pin be blocking the air?
Any time I air up the gun I always do it slowly...I am sure it is better for the gun, but mainly because nothing drains a tank faster than a leaking gun and an asa that is all the way on!
I was kind of thinking along the same lines as you are...it seems before that the regulator was leaking...allowing too much air into the gun. Now (after the reg is tight again) it seems as though not enough air is getting into the gun. There seems to be a restriction somewhere.
I will check out the pins on both the asa and the tank. Thank you for taking the time to help me out with this. If you think of anything else please feel free to offer it. I welcome any advice. Thanks.
