I got my engine back from the shop today. It's a 18 hp opposed twin. Last year I bored it, new crank, push rods, cam, and ground the pistons for clearance. He put on a new reworked carb and the new rings and it now 32hp at 3700 rpms. it will turn 4800 but it's not safe because of the cast flywheel. My Ultra Prop only needs 3200 tops any way.
