Followed pelicans suggestions, lightly oiled the cylinders, then wiped clean...

Pouring in oil would increase risk of stuck rings, no? I usually do this to see where air is being lost, here, I know its via the rings...

Found more posts about this on pelican. Some folks have had leak down losses of 30-40% after new rings (wow?!), were told not to worry until rings are seated. Others, are stating they had less then 3% loss across the board with fresh rings, unrun...

Will look at it again next weekend, with fresh eyes...

Sometimes I think not checking these things until after 500 miles or so is the way to go...
