    I have an exmark walkbehind model number TT4817KAC. While mowing at full speed it cuts out on me. I have replaced plugs and fuel filter and still have issue. Hopefully one of you guys can help me out so I can save some money not taking it to the dealer. Thank you!

    Guessing you have a Kaw 17hp...
    Check your valve adjustments....
    Those engines are also known for coil issues...

    Hey piston slapper, are both ignition coils on the Kawasaki the same part number? That's what I saw on a diagram. I had the same problem as OP and am fed up and just going to replace both coils.

    If it were only that easy....
    Before you replace the coils...tune it up and adjust the valves...
    The best way to check the coils is by installing inline spark checkers that flash with the spark..
    And of course...they don't flash when the coil doesn't make a spark....
    Always check the parts list for part numbers...

    Thanks, I have a mechanic checking it out. I had it in the shop twice last year and was told twice that I had water in the fuel. The second time it was in, the valves were adjusted. I've read so many times about kawasakis and bad coils. I've been using sea foam this season.

    Thank you. What should adjustment be? Or should I call dealer for that info?
