I am in need of an oversize piston for a243400 series briggs and Stratton engine. part # for .010 is 299086, .020 is 299087 and .030 is 299088. I really need a .010 over but would take what I can get for now, looking for new old stock to try and keep the price down on this rebuild.
I had one but it turned out to be standard size even thou it was marked as .010 over. PM if you have something
