he means cuts in the hoses.
Ok I'm probably gonna repeat there answers,
Your envy is set stock to run co2 if u use hpa change the dwell,
Look in the manual for info
Make sure there are no cuts
If all else fails take it to a local store or field
Im useing co2 and thats what its set for.... and cuts?
my advice: ummm.. check all your orings including your tank (i know it is probably not the tank but it wouldn't hurt) and if you can not find it anywhere then maybe its the regulator. you will have to take the regulator apart but you will need a certain tool here is mike's video on it
already checked all orings except for the regulator the sound doesn't seem to be coming from there but what might be wrong in there?
