I am in need of one only 4 ring piston for a 1939 Mercury T99 engine that is bored 125 over. This is the 3 3/4" stroked Mercs prior to the later 4" stoked engines of the 1949-53 models.
I picked this engine up and there was an internal clicking sound once I got it going. When I opened it up I found that the ring land between the 1 & 2 rings was broken away for almost 2" in length and the rings were what was holding it in place thankfully.
