BTW, I forgot to mention....

The needle threads in and out easily. The rachet is tight. The threads look perfectly cut. The O-ring is very slightly larger than the barrel and there are no symptoms of blow-by, it's sealing. The needle taper looks good and no burrs on the end. Looking down into the female structure shows no burrs. I originally had a needle extension, but pulled it in case it was causing some jiggling. No change.

I will be glad to post any closeup pictures if you wish.

Thanks for "listening". I hope you can help.
