| Hi and thanks for assisting. I have a Murray riding mower model 42544x8B that has a hard time starting when the engine is already warm. The only way I can get it to start is by removing the air filter. I cleaned the pre-filter fabric and also used compress air in an attempt to clean out the air filter. Is the issue simply that the air filter is too clogged to allow enough air to pass thru when restarting the engine? Once the engine starts, it runs fine with the air filter back on.
Thanks for any advice! |

| " Is the issue simply that the air filter is too clogged to allow enough air to pass thru when restarting the engine?

| Walt, I will pickup a fuel shutoff and install it this weekend. Question: what will shutting the fuel flow off before stopping the engine do to assist when restarting? Or is this just a first step in troubleshooting the issue? Thanks Walt! |

| They do sell replacement air filter cartridges! I have seen mowers where all they need is a new air filter installed, and then they start up easily! Blowing those things out with air only shoves the dirt further into the filter cartridge! RJ |

| It is possible that the float needle is leaking a little letting the carb flood when shutting off. After a few minutes, the gas may be evaporating to where it will start OR removing the air cleaner gives enough air to over come the slight flooding. You can pinch the fuel line closed if it does not have a fuel line shut off although a shut off is always good insurance unless the fuel tank is below the carb inlet. Walt Conner |
