    Weed Eater Lawnmower won't stay running
    I have a Weed Eater Briggs and Staton 300 push mower. I've changed the spark plug and cleaned the Air Filter. Lawn mower will start but immediately shuts off. Any advice?

    Sounds like you have a fueling issue of one form or another. If the mower sat over the winter and had gas in it, it's more than likely started to "gum" up in the carburetor. You can take come carb cleaner and shoot some down the throat of the carb and let it sit for a min or so then try to start and see what happens. If you still have the issue, you'll need to open the carb up and clean the bowl and jets.

    I could use the rest of the numbers. Watch the vedio again. If I get all the numbers then I may be able to PDF the whole repair/wire

    Meanwhile make sure there brand new high test gas in it and see how that does. I always test small engines with fresh high test.

    Mean while check for fuel filter that could be clogged and its not getting enough gas to keep running. The other reason I need all the numbers is I can get a blow out of the engine and see where the air fuel mixture needle valves are to help further.

    Do not tip the mower on its side before you try to start it (sharpen blades, etc... ) If you have give it 15 or 20 min. then try it.
