(it was causing problems),by making the piston rod longer and drilling an air intake hole in the tube. I had noticed that my piston o-ring looked pretty abraded and looking through the back of the compression tube I could see a very rough spot in the tube (manufacturing defect),the last 2-3" of piston stroke, so I've been grinding it smooth. One thing I noticed on this build is that the alignment of the link, piston rod and piston are critical. The piston rod is 5/16" dia. and does not flex. Hopefully I'll have some more results in a couple days.
