Several times now I put new rings in this troublesome motor I've been messing with, and each time after I pull her down again the rings have about an 1/8 inch gap. They went in there with about .012 inch gap, yet...

Is this normal after rings break in? The compression readings are holding at a reasonable level (and even increased a bit with running). In every case, the motor had less than a few hours running, and not at WOT for more than a few seconds at a time. Oil level mixture 30:1 initially down to 45:1 after break in.
