That could be the problem. You could check it by disconnecting the fuel line, sticking it in a small bottle and cranking the engine over. The pump is also often higher than the fuel tank or the carb to prevent siphoning.

Read the spark plug first to try to see what has been going on. A plug in normal condition has a thin layer of light-brown deposits on it. If you see a thick layer of black carbon deposits, it's a sign that the carburetor mixture is too rich -- your engine may even be smoking. Electrodes that have been worn thin are a sign of overheating, often caused by too much ethanol in the gas. If your plug has wet, oily deposits, it's time to take the mower in for servicing, because oil is leaking into the combustion chamber where it shouldn't be. · Other Engine Problems · If your spark plug appears to have normal wear -- or if you've just installed a new one -- and the engine doesn't fire, you can check the plug by replacing the spark plug wire with a tester and pulling the starting rope. If you don't see a spark on the tester, there may be a problem with the ignition coil of the flywheel to which it's attached. The ignition coil doesn't frequently develop problems, but the connection between the flywheel and coil or between the starting pulley and flywheel can wear out, and the coil may not be turning. Replacing the worn part isn't difficult, but you may need a pro to properly disassemble the engine.

I was wondering if it was a safety switch issue. Let me know. ... i would check the fuel shut off solenoid make sure it has power to it , and is grounded :thumbsup: also might check ground to" coil " i would disconnect kill wire and try it , also you can check the key switch and safety switches by hooking your test light on the + side of battery , turn key to on position if light stays on then it could be the switch or switches sounds to my like the key switch , but if you take the kill wire off @ the " coil" it will eliminate all wires just my 2 cents :thumbsup: i would make sure the wires are plugged in good at the wiring harness and clean the one near the engine , might be @ worst the speed advance module , but that would be where i went last , could be tank venting

May 21, 2024 -

I have a Simplicity Legacy 25hp (sub-compact tractor) with a Kohler Command Pro. It has 1100 hours on it, so its by no means a new tractor.

It has a problem now where it will run for 35+minutes, cut really good (no extra choke or anything like that), then suddenly bog down and die. it starts right back up but immediately dies as if its getting no gas (choke helps it stay up for a little longer but not much)

I've tried

New sparkplugs
gas cap off (vapor lock)
running each cylinder individually. It starts with either cylinder running seperately but still dies immediately after.

both cylinders get spark. The fuel filter has gas in it.

It doesn't smell like gas, get red hot, or make any smoke but the muffler is in pretty poor shape (original from early 00s) and it sounds like a cammed muscle-car so im guessing that is causing some extra heat. but i feel like there must be something else going on. So im wondering if anyone here has any other diagnosis steps i can take to pinpoint the issue?

I really dont want to take the carb off if i dont have to, so im planning on running a fuel cleaner. aside from that, maybe new coils?
