    Engine rebuild kit

    This kit is the most complete kit I could find and everything fit perfectly. Make sure to adjust ring end gap. The only extra item that I needed was the small points cover wire grommet.

    Hey just wanted to say I purchased a k321 engine rebuild kit from you about a year ago. I have the engine back together and running. It runs very good and starts up easily. I'm very impressed with the way it runs. Thank you for supplying the parts. It runs great!

    Parts arrived in a timely manner but the packaging was poor the piston and rings where loosely packaged and the center ring was broken during shipment didn't get the block and crank back from machine shop but everything else seams to be good

    Parts need to be packaged a little better to keep from damage

    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!
