Question about Craftsman 20 hp 42 in. Deck Yard Tractor
Less than one year old. Parked mower (running great) then 2 days later it will not fire. It turns over and can smell gas as I choke it or not, but will not fire. I've looked for loose or damaged wires on safety switches and pulled spark plug, all look good. The plug was wet with fuel. I am suspecting one of the 4 safety switches to be at fault, but not sure how to check them.
I could sure use some advice. Thanks, Bud
You need to find out if the switches are normally open or closed, that can be done with an ohm meter. Then bypass each one at a time either by just disconnecting the switch or by putting a jumper wire between the contacts (wires off switch). For example the seat kill switch is normally open while operating (no connection) it closes (makes connection) when seat is raised (rider off) and grounds the ignition to shut down the motor. Hope this helps

Usually the safety switches won't even let the engine turn over. One of two things is keeping you from getting spark. Could have a bad spark plug or the coil has went bad. Try a new spark plug first. To check for spark you can purchase a spark tester or you can remove the spark plug, ground the spark plug against the engine and turn the key and see if the plug is getting spark.
