Murray Riding Mower Shuts Off

I replaced the carb on my old 11 HP Murray mower. Now it will run for about a minute or so then quit. If I wait a minute and choke it, it will restart, but soon quit again. Any ideas?

Many people have this issue with their riding mowers.

  1. It sounds like you have bad gas in your tank.
  2. If you have left gas in the tank there is a thick sludge that will build up at the bottom of the tank.
  3. You need to empty all the gas out of the mower and flush your tank.
  4. Now replace the gas in the tank.
  5. You will need to check the spark plugs and replace this too.
  6. Leaving gas in a mower isn't good for the mower because the gas will evaporate and leave a thick sludge at the bottom of the tank.
  7. When you add new gas in the tank and run the mower the sludge buildup mixes with the new gas and clogs your carburetor again.
  8. I also would flush the new carburetor and make sure there is no sludge in the new carburetor.
