    Tuning Umarex Notos has arrived.

    I removed the barrel on my Notos and one of the two o-rings was cut in half. Does anyone know what size it is? Thanks!

    Oil recommendations for Yong Heng compressor

    I second this recommendation. I ran Royal Purple compressor oil in mine and it was dieseling in the second stage. Thankfully mine compressor started maxing out around 3700 psi after 10 hours of runtime which caused me to take it apart. The reed valves in the head were covered with carbon and...

    The top part of my second stage piston was loose and unscrewed by hand. Not sure what the best tool would be to loosen it. I put some red loctite on it when installing it and used some leather and vice grips to tighten it.

    The the top of the second stage piston unscrews where the second piston ring is. Once unscrewed you can install the lowest ring. The middle ring gets installed when you screw on the top of the head. I install the top ring last. I used an xacto knife to cut off the old rings.

    I figured out my problem. I disassembled the head and discovered the Royal Purple was dieseling in the head. The reed valves were covered with carbon and soot which prevented them from sealing fully. I cleaned off all the carbon and now it goes up to 300 bar. I ordered some better compressor...

    Tuning Tuning for efficiency and shot count (without forgetting precision)

    Tom, Thanks for sharing the results of all your hard work. I’ve got a 22 FX Impact M3 coming in a couple days. From your information above it seems like the second regulator should be set above 100 bar. What do you think would be a good starting regulator pressure for this gun?

    Tuning FX Impact M3 - Setting Spreadsheet

    This is a great idea. I’ve got a 22 Impact M3 600mm coming and was thinking how useful a database of settings would be. The google sheet link above isn’t working. Is there a new link? Thanks
