I’ll probably buy some just to try them, even though the 4 machines I use regularly all have metal needles in them and start and run well. I have had an issue or two with the metal needle, but since then I have tried paying attention to how the needle goes in to the primer face in relation to the 3 ribs running down the side of it. It’s hard to explain, but if I had them installed with one of the ribs pressing directly against the side of the primer face, it would stay straighter and slide up and down easier. It seemed the action of the float could make the needle go up and down on a slight angle in the primer face if it was oriented without a rib facing as I described above. This was with the primer cap off the machine, having a look at the cap, needle and float moving. I’m sure it would move when is use anyway. Not sure if that makes sense to anyone.
Cheers,
John
