    125 Automatic

    JD 125 Automatic won't start

    I was using my mower, but I had to empty the bags. At the same time the blade belt jumped off. After I put it back on it wouldn't start. Spark is good with me sitting on the seat. I even poured a little bit of gas into the intake to see if it would even start. Nothing. Like I said, it's got gas, spark but it doesn't even try.
    it's driving me crazy.

    scroll down left side of page to troubleshooting chart, let us know how it goes, thanks

    four things are needed for engine to run, fresh gas & air, good spark & compression.
