They are breaking at the pin. I just machined one so that it lines up with the sleeve at BDC and took the car out and ran it a little. Revs quicker and accelerates quicker. Don't know the long term effects yet, but so far seems to be a go. I'm not sure it's piston-rock. That is just something I'm wondering. Thanks for the response.
