Bob - do the Teflon buttons replace the piston pin clips?

If they do that reliably, as well as reducing rocking, and last at least 100 high RPM hours, they sound like a winner all the way around. I've never understood why J&E doesn't cut its pistons for a regular circlip, with ears and holes, so installing and removing the pins is easy.

I got used to the clips Mahle uses. Despite having Stomski's install tool, I still find the J&Es tough to install. And instead of just using a machinist's scribe or the like to remove them, I had to cut a notch in the end of a pin drift, which I insert in the relief and then twist so I can get a scribe in to start teasing the clip out. It all seems so much more difficult than using snap ring pliers.
