I'm building a 23hp Tillotson 225RS motor, it will be revving to around 9000rpm, using the key bits from my 20hp GX200, I have ordered a 225RS block, crank, piston kit from Tilotson...........but I have heard the Tillotson CNC con-rods are a bit suspect?........I notice the oil flinger is not drilled, I'm guessing ARC have some sort of patent on that, so I'm planning to order the ARC 3.465 CNC con-rod, dedicated for the Tillotson 225RS engine, which has the drilled oil flinger.........are there any bad experiences out there with the standard 225RS Tillotson CNC con-rods?
