Thanks for the reply, I was getting desperate. I always used HPA with the marker and currently have a Myth G2 regulator on a 48/3000 tank. Regarding the spring, I had a the silver medium spring and it was not compressed while stored. Regarding the power tube, I went through 300 shots with no problem besides velocity and travel distance.
I spoke to a local paintballer and he asked if I was using marker oil or grease. I currently use oil branded by Empire. He told me to purchase marker grease, clean out the gun, replace all O-rings and apply grease. And only put a few drops of oil in the ASA.
To be safe I will also replace the drive spring with the Harder Red spring.
Does that sound correct?
