I do realize I'm doing this part sorta risky like, but that's ok, I'm aware of the risk and am willing to get it running first, then tear it down again if I need to.
oh yeah, here's my reference, LOL
When I was rebuilding 2 strokes 'back in the day' they had a pin in the ring groove, specifically designed so that the end of the ring didn't rotate around and get into either the exhaust or intake port (can't remember which one right now).
cam chain feels tight. I lightly burnished the timing chain tensioner shaft and with the new spring seems to be doing what it is supposed to do.
Tonight I might be able to finish the engine assembly - if all goes well...
