Hi Gil,

Like I have stated before the "original" NVA for the FP is basically unobtainable now.  I never saw the LA in C/L form.  If OS made a C/L version of the LA then the NVA should work on both.

I have FP and FSR .10s.  They use the same NVA.   I have found a few NVA over the past few years.  Unfortunately the ones I have are in or slated for models.

And again, the "old" .10S venturi and NVA will not work.

             I do have a FP.10 but I never ran it. It's been said to me that these needles are unobtainable. Why doesn't the Max-S needle and spraybar fit. Is the diameter too large? Is it too small? Why doesn't the FP, LA .15 needle fit. I don't know the answers here so I'm inquiring as well. If too large, could the larger be turned down? Ken

HI Kenneth,

The .10"S" venturi and NVA are both too small to use in the FP.
