I would try plugging the equalisation hole, if that doesn't work cut an o-ring groove and see how that works out.

It did not work before the equilazation hole, hence i drilled the hole to ensure the chamber was being filled.
A floating o-ring can be used as a check valve. Gippedo's pump tutorial uses one. I'm not sure if there is enough flow through a schrader to get the ring to move, though.

That probably made things worse then. Have you tried wrapping tape around the piston?metalmeltr wrote:It did not work before the equilazation hole, hence i drilled the hole to ensure the chamber was being filled.

So you have an equalization hole and a check valve in the piston?metalmeltr wrote:It did not work before the equilazation hole, hence i drilled the hole to ensure the chamber was being filled.
In any case, have you verified that your check valve seals?

the eq hole is just behind the sealing face so it acts as a check valve

My old piston hybrid could pilot via the schader. Not well, but it worked. It used orings on the 2" piston, but it was not a %100 seal.
At one point I had a marble barrel hooked up and was charging it indoors. It was laying on the ground and the barrel was pointing toward my sliding glass door, and me being paranoid remembered "don't point a gun at anything you don't want to destroy".
So I nudged it toward the wall instead, and wouldn't ya know it my bicycle pump hose burst, pilotting the valve and imbedding a .62 cal lead slug in the wall a couple feet over from the door.
The piston hybrid version 3 had a 1.6" solid rubber piston with a floating oring, and actually piloted pretty good with a schrader. Note that I haven't posted 3.0, as it's currently disassembled and very far away.
