Sorry if this has been asked before, but this is my first time on the forum . I have an old Spyder 2000 (hardly used) that I just started using again. After about an hour of use, CO2 started venting from the regulator adjust screw. Tightening doesn't seem to make much difference. Is there any way I can fix it? Do I have to replace the entire ASA? Are there still ones available that will work with this model? Thanks in advance for your help.
