Acquired an old lawnmower that I need some help getting running. It's about 20 years old. It will start, run for about two seconds, then die. I know it's run in the past year, but I doubt any filters or anything have ever been changed.
My first order of business will be replacing the air and fuel filters. What else should I do? Lawnmower:

Quoted:
In addition to the air and fuel filters, I would put a new plug in it too. Drain the bowl and fill it with fresh gas, and it wouldn't hurt to spray some carb cleaner in to the carb and let it sit for a few minutes before you try to start it. Good luck! All this, but at this point might be good to pull the card and clean it thoroughly. |

This and when you have the carb exposed place your hand on top of the carb where the air goes in and seal it off. Pull the sterter cord a couple of times. This will normally dislodge any trash in the jets. |

Will it run on choke or in a position between full choke and normal run position on the throttle? If it will keep running or try to keep running when you choke it as it dies it is likely a clogged carb jet. You can also test for this with the air cleaner off and a can of starting fluid. As it begins to die give it a short shot of fluid and if it picks back up you know it has a fuel blockage. |

That is the same mower as used on trailer park boys "replacement assistant weekend trailer park supervisor", and incorrectly called a two stroke during the episode.
I know how to fix it, but the lack of fathers, trades, and shop class being cut for fag PC bull shit prevents me from sharing my knowledge. Your best bet is to buy a can of ether, aka starting fluid, and spray 1/4 can into the air cleaner, and pull the cord. After the explosion, just go to your latest big box store and buy another chicom motored shit box made out of scrapped American dreams and mow. Just kidding, I love you man.

I have a tractor too. Anyway, when starting it, I have the following sequence: pull air cleaner, squirt starting fluid in, pull rope, as it starts to die, squirt in more fluid. repeat this until the engine warms up and starts sucking fuel on its own. |

Repeat after me... Tecumseh carburetors are not worth a shit... I will never buy a mower with a Tecumseh engine. Now, let me be clear, the engine is GREAT, it's the carb's that suck. Best thing you can do is get a can of carb cleaner and a can of canned air and clean the carb. Remove carb Remove bowl Remove float Spray solvent in every hole, port, orifice Repeat last step Spray with canned air Reassemble and see what happens. Also, check the float for leaks, they are metal and have a nasty habit of filling up with fuel. If you find the o rings on the bowl are shot or just want to "correctly" rebuild the carb, you can get the kit here: |

Update:
Finally had time to mess with the thing today. Changed the spark plug and air filter, cleaned the carb, and put some Seafoam in the gas. Fired right up and ran like it was brand new. Which is good because my yard was getting a little shaggy. Thanks for the help guys. |
