My Kawaski engine Fh381v runs great at the startof the day

Customer Question

My Kawaski engine Fh381v runs great at the startof the day but after it has run on a couple lawns and warms up won't start again. Replaced the ignition and the fuel pump. Is there something I am forgetting to check? Do you think it could be wiring issues with the safety switch on the mower?

Check the coil gap. I would go ahead and re-gap coil(s) while you are in there. If you need instructions, please let me know. If it is not starting once warmed up, sounds like the coils may be getting too hot and you are losing the spark needed to run the machine

Let me know how the gap is and out come of re-gap.
