Lawn mower Dies after a few minutes?
My lawn mower (Craftsman 6hp) starts fine and works for a bit but then
starts dying. After trying this for a few times, then I have a harder time to start it. When I prime it and keep trying to start it, I check the spark plug and it is not wet from fuel, so maybe there is a fuel problem. I left it out side covered, but water might have gotten in anyways. So I drain all the fuel and drained the carburetor pan from fuel. There was no water in the fuel. I put new fuel, check the spark plug too. The only other thing that I can think of is that 3 months ago, I did hit something hard with the blade. It was making a slightly different engine noise for a month or so, but eventually sounded normal I think. Any ideas what else I could try? |

Until you mentioned that ran over a shovel thing (or was it a rake this time?) I was gonna say the carb is gummed up. If it's running too lean, you might try wrapping the air cleaner element with a damp paper towel to choke down the air supply. But check the flywheel pin; that's cheap and easy. Bob |

Just try loosening the cap a turn or so and see if it solves the problem. |

Its fuel or electrical, 2 minutes indicates when the carb is empty it dies so a fuel passage or float, does it start whan you force gas in by priming, then its fuel related. if more then a few minutes it could be the ignition module, see if you get spark after it dies, probably need a carb rebuild |

Gas lawnmower. I tried starting it today again it was difficult.
When I prime it I can smell the gas, I even see some in the air filter. But after pulling the rope many times to try to start it, I would expect to see a wet spark plug, but mine is always dry. Last time when I unscrewed the bottom of the carb pan, there was gas is the small metal pan. Maybe the problem is past that area? Thanks.

Gravity fed fuel or a pulse-pump to feed fuel? Sounds like the carb
bowl goes empty. I'd remove it and watch the fuel flow for say a cup of gas; is it a consistant flow or is it slow, just a drip? Dry plug says no fuel; Next is carb in the line. Then the fuel filter; those plug easily. Then the fuel tank, usually with a screen over the output, inside the tank. Tank could need cleaning, could be a plugged fuel filter, fuel not getting to carb, carb plugged or jets plugged. Not much more in the ckt. This could well be nothing but a plugged fuel filter; changed it too? Gas lawnmower. I tried starting it today again it was difficult.

Kind of a longshot but check your blade. This same type of problem happened
with my Craftsman. The blade was out of tightness due to hitting a wooden post. It sheared the little knobby things that hold the blade tight and it caused a tough time starting.. "lbbss" wrote in message ... yes put a new air filter. You have removed and cleaned the air filter?? Lou |

would fly wheel pin prevent gas from getting to the spark plug?
Because that is definitely a problem, I keep priming and pulling and then check the spark plug and it is dry as dry can be. |

I've seen on Tecumsehs, sometimes gasket between the carb and the engine
dries out. Might have to remove the carb, put a dab of Permatex #2 non hardening gasket crap on the both sides of the gasket, and bolt er back on. -- Christopher A.
