Ive googled as much as I can take and I cant find anything that helps my air leak.
My cyclinder set up is good and has rock solid compression when I test it (finger on air nozzle press the piston up makes compression and doesnt leak at all). Now when I install the cylinder/piston assembly with the tappet plate in the gear box... the air nozzle leaks. I try the same test while its installed in the gear box (finger on nozzle press the piston in) and I hear the release of air from the air nozzle.
My best guess is the tappet plate is pressing on the air nozzle in such a way that it makes a leak. Ive read about shaving the tappet plate but I dont think that would help as that wont adjust the angle of the plate and how it sits on the air nozzle.
Any thoughts/ideas?

You can buy an aftermarket nozzle with an inner O ring. I had this same problem and it fixed it.

I have a guarder air nozzle already installed that has an oring. It was at 350-360fps now its down to 180-200.

Try lubing it up with some very thick silicon gel. That's always helped me fill any gaps and keep stuff tight together. I use Super-O Lube. Generally used for O-rings

I have ran across this problem in the past before too. What I did was I started by using Teflon grease in the cylinder and applying Teflon tape to the cylinder head just as a precaution to keep the best air seal. When you test the assembly out of the gear box and it holds all the pressure is just because you maybe pushing down on the air nozzle against the cylinder head creating a tight air seal (it took me forever to figure that out). When you insert the tappet plate, it lifts it from the cylinder head and creates a gap letting air out. This next step is what will solve your problem (hopefully), to get a full air seal, you can use Teflon tape around the cylinder head and then some Teflon grease. Put just enough Teflon tape to close the gap between the cylinder head port and air nozzle but not too much or you will hinder the nozzle movement and warp your tappet plate. the Teflon grease will keep the Teflon tape in place and allow the nozzle to move more freely.
If you are confused or need help (like pics and step by step), just PM me and I will be more than happy to help.
