The other ones are .17 in the hole! I came up with the number for the KB's by subtracting the difference in the compression heights.
I am also doing all this with a dial caliper. All I got. Not the best. I looked at the measurement fifteen times, thinking I was misreading. If this monsoon clears up I am gonna take some pictures.
Whoever did this rebuild used the wrong pistons for the application. They probably built it, and was disappointed that their "new" engine lost power. The engine could probably have run on Kerosene!
