More proof that the left piston is on the wrong side and visa versa. My original post said to use a very long screw driver socket (attachment) next to the piston – then you can use an impact driver to loosen the screws. Swap assemblies with new piston rings. (After deglazing the cylinders) I am sure there is a roll of 2-½” piston rings in the garage at the Cottage. We got them in packages of 100. Unfortunately my sister locked it up when she left and won’t be back for 4 months. We also have a jig to hold them while we cut the notch for the alignment pin.
