Unable to get over 250 fps

I have a ANS 5 autococker that sat for over 5 years and I can't seem to get it to go over 250fps with out making the reg pressure about 750 psi. I removed the valve and cleaned and oiled it, cleaned the ramer on lower internals and cleaned the hpr. I have sweet spotted the hpr and the ivg is now about 7/8 of the way in and still not reaching the desired fps. Hpr pressure is at 350 now...

Set up is a Detonator reg (tried a Gladiator ll reg off of a droid and same result), ANS ram with 2 QEV, Derlin venturi bolt, ANS 3 way, Any ideas??

You may want to try sweet spotting it again, back the ivg out to where it is only two threads in and lower your reg pressure all the way. Increase the pressure slowly while watching the fps until the fps decreases with any increase in pressure then back off till it the peaks. Once you have done that you should be close. Set your ivg to the desires fps from there and you should be good to go. Most of my cockers sweet spot around 260-270fps regardless of the valve and my karni sweet spots at around 285fps.

Sounds like you need to fine tune your springs. There shouldn't be a need to crank in the IVG more than a couple turns to reach desired FPS.

The first thing to try is a new mainspring. When the gun sat for 5 years was it cocked? If so, your mainspring is probably worthless.

Beat me to it. Try a new main spring.

New mainspring definitely. Maybe a softer valvespring. Stock internals? And consider a bit lighter valvespring...does wonders for efficiency and operating pressure, not to mention, its quieter

Valve spring is all i could think of, unless you used a lot of thread tape, then it could be plugging stuff
