SOURCE: my riding lawn mower won't start it has a spark

Assuming " won't start" meaning cranking but not getting fired, otherwise my suggestion won't be valid:Try to put some gas into the carb to see if gets started. It is started then died then gas is not delivered to the carb.

24 hp Craftsman lawn tractor will not start; doesn't appear to be getting gas in the carb. It is pumping through the fuel pump.


hi Vet68652, I have to agree with tomicamel, it does sound like a clogged fuel filter there is nothing else between the pump and the carb.... unless the line is clogged,

Two things:
1 Is fuel coming out of the fuel line. Older mowers have old fuel lines and they tend to get weak and collapse went they warm up with engine heat. Replace the old fuel line.
2 deposits in the carb. take off the air cleaner, start it up and spray a good carb cleaner in the carb until the engine dies. Put some 'seafoam' in the gas and a little in the oil and put the air cleaner back on and start the mower and mow on FULL THROTTLE. this should claen out the carb. Yes the mower will run rough for awhile.

these two cheap fixes will solve 85 % of carb problems. GOOD LUCK

Lawn mower dies when it gets hot when it cools off it starts until hot again I've changed the coil and module


you should change the oil and make sure you are using a good oil. Also, make sure your fuel line isn't running next to any place where it can heat up.

I have an old Craftsman 286707 riding lawn mower that will turn over but not start - ideas of where to look - it worked fine 4 days ago for the first time this season but took about 5 tries


Did you have gas in it over the winter? I would try some starting fluid and see if its fuel related or something else.. If it will run with a little starting fluid for a minute then you have some kind of fuel issue.. Gas with ethanol blend is bad for carbs over the winter. .. I would use some really good fuel stabilizer once you get it working again.

Mower runs ok until i engage cutting blades then engine starts to cut out and backfire


Could be a few reasons for this..
First try a new spark plug, new gas filter, clean the air filter and check the gas line for cracks or leaks..
If the issue still exists - try spraying some carb cleaner into the intake while it is running in short controlled bursts..
Or the carb might need to be rebuilt.. If it sat for a long time - the gas in the carb will shellac and cause it to not work properly.. Or it could be a bad float in the carb..

Good luck..
