Riding Mower Problem

[joewilly]

It is a 2011, Troy-Bilt Pony, 42 inch with a 17.5 hp Briggs and Stratton engine. I picked it up last summer and
completely tuned it up, plugs, air and gas filter, oil change, new battery, replaced old gas with new gas, etc. It
has been running great until last week when the engine quit while I was cutting my lawn. It will turn over, but will
not start. I did the standard troubleshooting, even removing the spark plug and squirting some gas into the engine,
and it will not kick over. Any ideas before I trade it for something else?

Did you check to make sure the carb didnt lose a screw or that its not out of whack?

Is the spark plug getting a spark?
Have you visually confirmed that by grounding the spark plug tip to some exposed metal part of the engine while you crank it or a friend cranks it for you?

If no spark, check the wires and contacts on the Kill switch that is attached to the seat-- the one that is supposed to automatically shut off the engine if you lift your body weight off the seat.

Sounds like no spark. Did you hold the plug close to the block to see if it arcs?

Fuel, fire and compression. Need to make sure you’ve got all three.

Beat me to it. I forgot about the seat sensor. Not sure how though, I had one give me a hell of a fit because of that. I ended up making a jumper for it.

Wait, I see the problem in your photo.

Your mower doesn't look like it should.

It needs to look like THIS:

It won't be the seat sensor since when you aren't sitting in the seat the engine won't turn over at all. Could be dirt in the fuel line or bad fuel. If the mower (I have the same one) has set up with fuel in the tank it could easily go bad.

Make sure your getting the correct voltage from the battery.
