Gil,
Does the piston wrist pin just push out or are there screws holding it in from the underside of the piston. Think i will do this to lower the compression as well. Thanks for taking the "risk" for us!

The wrist pin pushed out easily. On the horizontals I have some slide out easy and some seemed pressed in and would not move. Pressed or glued?
