    rebuild kit carburetor

    everything in the rebuild kit was great no problems except the carburetor the float was set to low and would flood and I'm still trying to get it adjusted correctly also I changed the float shaft and the choke plate did not fit in the carb correctly I had to ream out the screw holes one way to get it to fully close and open.

    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.

    I'm very impressed with the way it runs.

    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
