    Ok guys picked this little baby up at a yard sale for 5 bucks. I figured you cant have enough mowers so i got it. I took it home 2nd pull it fired right up. I changed the air filter and spark plug and mowed my lawn. That was about 3 weeks ago. I had it in the back of my shop and decided to pull it out again. Now no fire. whats wrong???? any help will be greatly appreciated.

    By "no fire" do you mean no spark?
    If not, did you check for spark?
    Fuel valve open?

    Pull the carb off and clean it. I think you can do a quick check by loosening the bolt in the bottom of the bowl. If I leave mine sitting out, that is what I have to do to get it running again. I don't have room to store it inside.

    Also, spray a little ether in the carb and see if it fires. That will let you get to the gas/spark part of the question.

    If you don't have spark, it pretty much leaves it as being the coil, assuming you are getting a good ground to the plug.
    I have an 18+ year old Masters. I mentioned the fuel valve, since it appears opposite of what one would expect for it to be open.
    When I start for the first time after winter storage, I usually have to dribble about 1-2 teaspoons worth of gas in to the carb throat. After that, I'm good for a year.
    Don't use starting fluid. If you need a prime, use a bit of gas. If that's the problem, it'll either start or not on 1-2 pulls.
    Maybe there's a reason it was $5? Coils are kind of spendy, but the mower is still worth it if the other parts are functional.

    No spark? I'd first check the flywheel magnets for rust. If rusty, clean with wire brush. Clean the two little magneto arms with fine sandpaper too, which gets the charge from the flywheel magnets. Check the gap, adjust. Use business card to set gap.

    Check for spark.

    If still no spark, I'd replace the ignition coil. It's going to cost more than $5. Sorry.

    Definitely clean off the rust!
    As Mark in MD said.

    That mower must have been stored in a very damp place!
