    Very high quality

    Just got done with a complete overhaul on my k321, bored .020 over and crank ground .010 under. The machinist said that the parts were good quality, the exhaust valve non magnetic, connecting rod bore round unlike most aftermarket and piston was good also. It fired right up after assembly and I mowed for 2 hours with no problems. Everything is looking good. Thanks Norman!
