kersplat, when I first put the sleeve back in the case I had it lined up like a typical Schneurle (I was paying attention to the case bulges) and I wondered to myself what was going to keep the Teflon pads from catching in a port.

Then, when I looked into the exhaust port to line up the sleeve I saw that it must be rotated back several degrees. Sure enough, as you point out, this allows the pin to ride over bridges on the sleeve. This is when I removed the sleeve again and discovered that the bulges are only cosmetic. I can tell I followed in the same exact footsteps as you.

To be honest, I really hate removing and replacing pin clips on anything smaller than a forty. So, I'm glad this engine was designed this way.
