    Great overhaul kit.

    This has to be the best kit I have ever purchased. I don't think they missed a part. We will see the quality of the parts later on down the road. I am impressed on what I have seen, this will be a complete overhaul that may equal a new factory engine. I would highly recommend this to a friend. I just hope I can remember where all this stuff goes, LOL

    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.
