regulator mod

Hi everyone,
mod fitted but I was wondering if others have fitted the small spring from the original valve, I noticed the new valve
doesnt have a hole drilled to locate it so maybe its not needed, what doyou think.
I know the spring is only there to keep the valve against the port face , once pressure is there that will
keep it down, just wondered what others have done.
thanks
Kev

I didn't fit mine as it didn't seem to sit in very easily

None on mine or Andy's.

Thanks chaps,
If its good enough for Kev and Andy its good enough for me
Thanks
Kev
