We’re both e-clips still in the piston? There’s a larger bearing on the big end of the crankshaft also, on a lot of the cylinders there’s casting flaws that need to be removed, I got a cylinder in a couple of months ago that was real bad. That’s why I take a new engine down and clean up what should have been done at the factory.
That’s on a steel sleeve cylinder to show how some look, I have a G4 type cylinder like yours that had some of the same.
