I have a 12 HP craftsman riding mower. When it gets hot it begins to miss a stumble. If I continue to use it I have to have it choked, if I keep going it then stalls. What do you think is causing this?

After reading another post about stalling in here, I think I found the answer. Mine (16 hp) would stall the same way, after about 20 minutes. I loosened the gas cap and it kept going. I think the vents on the cap are clogged, which prevents the gas from going through the line. I will clean those or get a new cap.
Thank you. I had changed everything on the lawnmower, and was having problems with my lawnmower stalling. I had adjusted the idle speed screw and the idle mixture valve; but nothing worked. Then I read the post about the gas cap. Wow! The light turned on. I had lost my gas cap.
I have a 24hp Craftsman Briggs and Stratton riding lawn mower. It will start up and run in choke for a minute, then it dies. I have drained the tank and put fresh gas in. I have sprayed carb cleaner in it. If I keep spraying carb cleaner it will continue to run. I can't figure out. Any suggestions?
Fuel Filter needs to be changed out. It's either dirty or water has gotten into the system.
The piece at the bottom of the float bowl needs to be replaced. Had the same issue. Drain the fuel, then undo the from the bottom of the float bowl and replace it. About a $20 fix.
I have had simular problems with my old craftsman. I have figured out my problem. I took the fuel filter and cleaned it along with the fuel lines. When you put gas in it, over time, sediment sinks to the bottom of the tank. Then later, the sediment gets sucked into your lines witch can clog your gas filtering system. The engine isn't getting the gas it needs for the amount of air it intakes which can lead to stalling.
My Craftsman 6.5 hp lawn mower runs on prime then stalls immediately. I replaced the plug and filter. I am getting the same result any Ideas?

Just before this problem occured, were you getting heavy black smoke out of the exhaust?
If nothing else works, look for your fuel bowl underneath the carburetor. You'll find a 'bolt' on the bottom of the bowl. Drain fuel tank 1st, then remove this 'bolt from the fuel bowl. You'll find that the 'bolt' is what's commonly referred to as a 'banjo bolt', and will have a small hole in the top, and 2 smaller holes on the sides where your gasket/washer is on your banjo bolt. Clean any foreign matter out of this bolt, blow it clean, and re-install. See if that won't work to keep it running, as those holes in your banjo bolt is what allows the fuel to flow freely into your carb.
You can start the mower, but if you release the clutch or engage the mower deck the engine will die.
The kill switch may be faulty or completely dead. There is one under the seat and one on the brake pedal. Replacing both switches is best.
I have a Craftsman garden tractor with a 54 inch mower deck - model 917.28749. The engine runs fine, but it stalls whenever I engage the drive (all speeds) or engage the mower.
I had the same problem with my LT 1000 Craftsman riding mower. I tried everything I could think of. What finally worked for me was a new gas cap AND a new fuel solenoid located on the bottom of the carb bowl. No more problems. I don't really think the new cap fixed it but wrote that in anyway. The old fuel solenoid saw a little sticky when pressing down on the valve on top of it. Hope this helps you. It did me.
I have a Craftsman riding mower and it mows for a while then it dies. I get it started back up and then it does it again. So what is it?
I would check both the carburetor and the fuel line.
There are several things wrong with your mower that could cause this to happen.
You could have challenges from as simple as condensation in the fuel line to a short or loose wire, on up.
You may want to check with their customer service and get their expert guidance! They can also tell you if there are any recalls that could be a free fix:
Let me know what you find! Good luck!
I have a Craftman lawn mower with a Briggs and Stratton engine. It starts and runs fine, but when you put the deck on, it dies. Any suggestions on what might be the cause?
There is something called the operator presence switch under the seat. It will stop the motor if it senses there is not weight on the seat. It may be disconnected or may need replacing.
Most of the time this type of problem has a simple fix but you need someone to walk you through it. Try contacting your local Sears service center (Google Sears service center with your zip code) and give them a call.
here is a link that has some suggestions.
here is a link that has a lot of troubleshooting videos for Craftsman mowers. You can also find a manual or ask your question on this site.
Words that involve 'deck' says:
- Blades could be bent? Is there any noise with the deck though? Or any scratches? Could need a replacement blade
- Might need some cleaning if "excess of grass, mud, mulch and/or twigs built up within"

I have a Craftsman 18.5 twin that will start but only run for a minute or two then die. If I use the choke, it still quits running. If I smother the carb with my hand, it chokes it enough to run a little longer. I replaced the fuel filter and cleaned the carb. My thinking is that something gets hot and cuts the flow of fuel. Also, it's gravity fed and the vent on gas cap is clear.
buy this fuel filter for it part #25-050-21-S its a 75 micron not a 50 or universal one
I have a 24 HP. Craftsman mower, with only 15 hrs. After riding it 1/2 hour to 3/4 of an hour it backfires and shuts wown. After sitting 10 minutes it restarts and shuts down again. Sometimes I rev the engine up and down and it corrects itself.

It sounds like your choke is sticking. Have you checked the choke and throttle and also made sure no debris in the fuel line?
My Craftsman riding lawnmower stalls when I ride it after a few seconds. Then it won't start till I charge the battery again. What's the problem? The battery is new.
How's the spark plug?
My Craftsman lt1000 20 H runs until it gets hot and then the engine quits. I've changed the fuel pump and the air filter. Could it be vapor lock? If so how do I fix?
