Last week while mowing the lawn my mower started to stutter like it was running out of gas. If I stopped for a minute it would rev back up and I could keep mowing. I barely made it though the rest of the yard before it stuttered to a stop.
This morning I went out to mow and the damn thing will not start up. It's a Craftsman 6.5 hp push mower. I checked the plug and it's pretty fowled but looks good. What should I check next any sugestions for a fix? It has gas and it appears to be getting to the cylinder. UPDATE: I cleaned the carb and drained the gas and started with new fresh gas. Immediately after cleaning the carb Ican start the mower for a few seconds until the carb cleaner burns off. I checked the fuel line and the tank everything looks good there. Fuel is getting to the carb bowl but I'm not getting any ignition. I'm thinking about running out and buying a new mower What do you guys think of this one. Husquvarna Mower |

Perhaps water in the carb bowl...drain it and try again.

Fuel filter? Clean the carb up. Shouldn't take more than 20 minutes to check and clean the carb. Good suggestions. Also remove the fuel bowl, clean the bowl, float and needle / jet. Be careful not to loose any small parts. Small engines are funny like that, with the new formulation of fuel it doesn't take long for it to spoil and foul the carb. Also the smallest speck can clog the flow needle. If you have carb cleaner when you remove the bowl and needle also remove the spark plug to relieve pressure, stick the cleaner straw up into the need hole and shoot a good amount up there. That will clear the passage and allow proper fuel flow. Also check your plug gap it should be between .28 and .30 thousands of an inch. Best of luck. |

pre-1. Always use a fuel system treatment on your lawn mower fuel. Over a week, fuel will loose much of it's volatiles and become more prone to varnishing parts of the engine. 1. Check the fuel line from the tank to the carb. Ethanol treated fuels eat fuel lines for lunch!!!!2. Check the air filter for clogs/obstructions 3. Check the carb for junk, clean the bowl 4. Spray carb cleaner in the jets, & clean the float valve on the carb 5. Clean the runners in the carb |

Just dealt with a similar problem this past week
Mower was running really rough, but made it through the cut 3 weeks ago. 2 weeks ago, no problems Last week, the engine would start after priming it, but then immediately turn off. It is a Briggs & Stratton motor, so I used their site to find model # and replacement parts. I picked up their maintenance kit for my motor at home depot for $10. Air filter, oil, spark plug, and fuel additive. I also picked up a can of carb cleaner. Cleaned out the carb and replaced all the maintenance items. Runs like a champ ETA: my fuel is several months old as well and needs to be replaced |

Pull the carb and give it a good cleaning. Chase all the orifices with a wire or welding tip cleaner. There should be two or three small orifices in the carb throat near the throttle butterfly, don't forget those. I usually pull a strand out of a regular multistrand electical wire and bend it into an L. If that doesn't work, you can probably get a carb for 50-60 bucks. Have your model and serial numbers on hand. |

That has been one of Sears' most popular lawnmowers this year, at least it was at the store I worked at. We couldn't keep it in stock, even having to sell the floor models more times than I care to count. Did you see any of them come back. I really like husky stuff but I'm not so sure about the Kohler engine. |
