Have a WG7, pistons have no pins in the piston ring lands to keep the rings from rotating.Apears there never were any there.I find this unusual on a 2 cycle engine. has any one ever seen this?
I have found a few motors where the piston ring pin had "floated" out of the top of the piston and thus were missing. Some had just receded out of the groove but were still in the pilot hole on the top of the piston.
