Retro sputtering?

[p8ntbalr2004]

Hi, I have retro valve, bought on 1/25, that sputters pretty badly. Sometimes it is just at the beginning of string of shots, other time throughout the whole time. I think it is the PT spacer? Sound right? I currently have the .220 in, and have tried the .215, but it still sputters and seems to fire almost full auto.

Any advice?

Thanks

usually when it sputters, not enough input pressure to the valve? tank filled all the way? and if you have a adjustable tank, is the input pressure at least 800 psi?

tank is full

Yes, the tank was just filled. Its a PMI preset 114/3000. Im guessing the input is around 800?
thanks

maybe turn up the velocity on the valve? not quite sure but I know someone on this forum will answer your question

Make sure to run plenty of lube through it too. Mine was doing that too.Run alot through until it runs right.
