    Looks like I found a rebuild kit that has a .50 over piston.

    Worse case I am looking at $50 to rebore, $20 for a valve job and $125 in rebuild kit. Looks like I could be done with it for less than $200.

    Hmmmm......
    $50 to bore a twin cylinder .????
    Its gonna take an hour to build a jig to hold the block in the boring bar..
    $20 to do all the valve and headwork on 2 heads .???
    Resurface the heads...ctean the heads and valves...cut and seat the valves..
    I hope the machine shop doesn't butcher your parts...

    Sometimes.....you get what you pay for...
    Good luck

    It's a local shop. They did the engine boring and valve job on my four wheeler last year and it turned out great. They have the best prices around as well.

    Ok....sounds like you know what to expect....
    :;
    I have built hundreds of commercial engines for paying customers...
    I personally wouldn't take a mower engine to an automotive machine shop..
    They caused me so much in damaged parts and shotty work...
    Not to mentipn the pissed off customers.....that I now do ALL my own machine work..
    Try to get your money back...or parts replaced from a machinist that just butchered a customers engine...
    Hope you get what you pay for...

    The shop is Massey Machine Shop in Jackson, Ms. They are the most reputable shop in the central Mississippi area. The do a lot of small engine work for Got Gear (Honda, Polaris, Yamaha, Kawasaki) and John Deere Dealer (Mississippi Engine). They have also done work for me and other friends with out having a problem.

    I am an engineer and know what questions to ask and what to do to minimize problems.

    I appreciate the advice and warning, but I am a seasoned "mechanic", just not on Kawasaki engines.

    I am now trying to decide on the rebuild option or the Briggs & Stratton Vertical Engine 21 HP Professional Series OHV 1" x 3-5/32" #33M977-0003. $400 seperate the two options.

    Well I picked up the project tonight. Looks like I will definitely need a muffler. Talked with the owner and his mechanic said it had very low compression and was using tons of oil. I would say I have plenty of room to work considering I paid $250 for it and it came with a two wheeled sulky.
