free lawnmower not running quite right
Hello,
I was recently given a lawnmower with a Briggs/Stratton 6.5HP motor. I was told it might need tuned because it hadn't been run for about 5 years. When I first put gas in it I noticed it started to leak the fuel behind the primer button. That was on Friday night. Saturday when I tried it again by putting more fuel in it the leaks didn't reappear but after priming the engine started but would immediately stop. As long as I had someone continuously press the primer button the engine continued to run just fine. So the spark plug was working, fuel line was clear, etc. Today I took apart the carb except for the float bowl that housed fuel near where the primer button is located. I attempted to take that component apart as well but couldn't get the nut on the bottom loosened. So I just cleaned the carb as best as I could but I didn't see anything clogged and my cleaning was mainly done for aesthetics. Short of taking the mower to a pro for maintenance can anyone tell me something that could put me on the right track to fixing it myself? Everything I read online made it sound like it was a carb issue but I didn't find any problems unless they were in the float bowl that I didn't take apart. The advice I found said there would be a pin/screw with a pinhole in it from where the fuel would be ejected and that it was probably clogged thus preventing normal flow of fuel. But I never found anything like that in my carb. The place where it looked like fuel was inserted was more like a tube sticking straight up and I couldn't get to it since it was above the area I didn't take apart. Since that small tube was inside the primer button component I couldn't look in it to see if it was clogged. For anyone who happens to have (or wants to download) the parts list for my B&S engine, the model is 121602-0190-E1. It is an Intek, not the Quantum type. Oddly enough, looking at the owner's manual both types are supposed to have a Safety Key but mine doesn't have that. I was working off page 4 of the parts list PDF file to determine the names of the parts I was working with today. Part #975 is the float bowl and part #134 I think is the small "tube" that fuel comes out of when operational. What are the odds that is clogged and that priming the engine constantly would help work around that particular problem? This mower has a bag also. The bags aren't required to be on for the mower to work are they? As you can tell my knowledge of mowers is slim to none. I'm a recent first time home buyer so I'm learning. Any ideas? thanks Brandon |

Any ideas? thanks Brandon Get carburetor rebuild kit at a dealer. Replace any "flexible" parts such as the diaphragm. Any part you think looks bad can be replaced, also. But avoid replacing things just because you got a new one unless you want to make more trouble. |

I'll target the float bowl next time I work on it. Figures that the part that I didn't look at in-depth is the thing that is most likely the problem. If this doesn't work I may just buy a carb kit but if cleaning the float bowl and the main jet don't do it then maybe there are bigger problems which a new carb won't fix. If I'm lucky I won't work too late on Tuesday and I can try it again and report back in a timely manner. I'm in the US Damian so I prefer to not call international if I can help it. thanks guys for the quick responses. |

The needle-size hole in the bolt keeping the float bowl together was crusted up so I ran a paper clip through it to clean it. It is wide open now. I also ran the paper clip up into the main jet but it was clean. I put everything back together but the mower still stalls unless continuously primed. Could the float be screwed up and need replacing? What else could be causing the mower to stall? Should I get a new spark plug? thanks |

I read your post and I was thinking about what you said about the primer bulb . And how it ran as long as you kept priming it. Sounds like to me you have a primer bulb thats not holding a vacum. And maybe a fuel fitler thats dirty and not letting fuel flow freely. Worth a try. Good luck |

Sometimes the sheath on the throttle cable can slip and the choke will stay closed and it will run for a few seconds or so and then die when the engine starts to warm up. I've read that a sheared flywheel key can cause the engine to die suddenly but it's never happend to me but should be easy enough to check for. |

I forgot to say: will it continue run if you hold the thottle open on the carburator? That might mean a weak governor spring. I like free lawnmowers. I have three of them. So far none have had any serious problems that couldn't be fixed for next to nothing. |

The bags aren't required to be on for the mower to work are they? As you can tell my knowledge of mowers is slim to none. I'm a recent first time home buyer so I'm learning. Any ideas? thanks Brandon You need to get the float bowl off and clean it out along with the main jet. If the nut will not come off then you'll need to replace the carb. OK. I'll target the float bowl next time I work on it. Figures that the part that I didn't look at in-depth is the thing that is most likely the problem. If this doesn't work I may just buy a carb kit but if cleaning the float bowl and the main jet don't do it then maybe there are bigger problems which a new carb won't fix. If I'm lucky I won't work too late on Tuesday and I can try it again and report back in a timely manner. I'm in the US Damian so I prefer to not call international if I can help it. thanks guys for the quick responses.- Hide quoted text - - Show quoted text - After installing the replacment float, be certain to set the drop just right. As I recall the rebuild kit has a little cardboard gauge that will help you adjust the tab that activates the needle valve. I took apart the float bowl of my lawnmower. The needle-size hole in the bolt keeping the float bowl together was crusted up so I ran a paper clip through it to clean it. It is wide open now. I also ran the paper clip up into the main jet but it was clean. I put everything back together but the mower still stalls unless continuously primed. Could the float be screwed up and need replacing? What else could be causing the mower to stall? Should I get a new spark plug? thanks Can you see the choke by removing the air cleaner? Sometimes the sheath on the throttle cable can slip and the choke will stay closed and it will run for a few seconds or so and then die when the engine starts to warm up. I've read that a sheared flywheel key can cause the engine to die suddenly but it's never happend to me but should be easy enough to check for. I forgot to say: will it continue run if you hold the thottle open on the carburator? That might mean a weak governor spring. I like free lawnmowers. I have three of them. So far none have had any serious problems that couldn't be fixed for next to nothing. Governor spring don't get "weak". Unless someone like you is pulling on them and bending them ways they aren't supposed to go. -- Art |
