    1. New Fuel
    2. Have Spark
    3. Took off the fuel hose to the carb bowl and it is coming out of the hose
    4. Sprayed starter fluid in carb, eventually started for 10-15 seconds

    Any ideas on how to get this bad boy going? A friend of mine said the valves may be bad, but not sure at this point. The kawasaki engine is in a tough place on the F525 so maintenance is a pain.

    I wouldn't think it is ecectrical if it does start with starter fluid. I noticed on the bottom of the carb bowl there is a small module with a wire connected to it. Is this a pump or sensor of some kind? Wiring heads up to the switches and such.

    Lastly, if I keep cranking the engine, after 20 seconds or so it backfires, but still never starts.

    Your wire in question is the fuel shut off. The default is closed and when you turn the key on it opens. So when you turn the key you should hear a click noise from it. That might be your issue.

    It clicks when I turned the key. I was hoping that was it!

    Ok so if you turn it over for a few seconds and it won't fire pull out the spark plug and see if its wet. If so then your getting fuel and now we have a spark issue. You said it backfired, does it do then while running on starter fluid? Also can you keep it running with starter fluid?

    I pulled the plug, cleaned it up, coated in carbon, then cranked it again.

    It smelled of fuel and was black again, some slight moisture, not a significant amount. Haven't tried the starter fluid yet.

    if its got fuel then its a spark issue or spark timing issue.

    He said it started after starting fluid sprayed
    What's the history of this thing? Sitting forever? Died while operating?

    I pulled the shroud and flywheel nut, timing pin looks ok. I saw the spark plug is not the same part number The jD manual calls out for. I'll have to wait for JD to open up on Monday you know of a good replacement plug I can pick up at autozone or lowes

    True but its easier to run starter fluid with bad spark.
