Mower problems
I have a Craftsman mower with a 6.5 hp B&S motor.
It didn't want to start this season. It has good fresh fuel and I tried a new plug. When I pull the cord there is nothing. When I pulled the plug it was wet so I assumed that was the problem. DIdn't help either. I sprayed starting fluid and it fired and ran for a moment until the spray went away. If it was electrical it would not have run. Since it ran on the starter fluid, it must be the carb,,, right? I am assuming that maybe a jet is plugged. Am I heading down he right path? Thanks |

Might be water in the carb. You've covered everything else - except maybe the float needle valve is stuck open. And it's getting too much gas. Is there a choke on this thing or is it the kind with the primer bulb ? I've had the little tube to or from the primer bulb crack and break. |

I can hear the fuel bubble as I push it so I don't think it is bad. I am going to try to pull the carb tomorrow and see what I can find. I hate to give in yet and take it to a shop. Hopefully it is something obvious. (I didn't think about the clogged jet and wet plug. Thanks for throwing that out there) |

Thanks Wet spark plug spells either too much gas, OR, not enough air. Clean and oil the air filter first, then work on the gas thing end if not successful. -- Dave |

Last used in latter end of October last year. All started fine in early March. But, I also have experienced the old gas thing while storing an automobile for 6 months or longer at a time. A full tank helps keep the moisture condensation problem down to a minimum. "Dry gas" additive should be used if storing approaching a year. Not related to fuel, but important, always disconnect the battery. Am guessing some this carries over to lawn equipment with gasoline engines as well. -- Dave |

I've never had trouble starting my tractor, chainsaw or stringtrimmer. I believe leaving the gas in the machines keeps the gaskets and diaphragms flexible whereas running it try lets it get hard and crack. Sometimes doing nothing is better than breaking things. |

Replace the air filter and make sure there are no cracks in the air lines if
it has any. Make sure there is no old lawn clipping build up under the mower as some access their air from there. -- 909090...J Message posted via HomeKB.com http://www.homekb.com/Uwe/Forums.aspx/gardens/200806/1 |

Sound like your carb needs cleaning out. A compressor is the best tool for the job. You can also leave it in paraffin (kerosene) overnight (not the rubber seals though)
