MTD Supreme won't stay running

busyMay 3, 2010

Hey everyone,I'm new to this forum and have found some good info. Anyhow I have a B&S 10HP motor on my MTD Supreme Rider. Motor model-type is 255707-013301. It will run for 10 minutes or so and then miss a few times and just die. It has to cool down good before it'll start back up. Background info is that I bought it from an old lady for $175 not running with flat tires and had been in the a shed for a few years. However it looked like it had been well taken care before the lady's husband had passed away. I've cleaned the carb, changed oil, fuel, fuel filter, spark plug, and cleaned the air filter. I'm $250 into this project and want to try to fix it myself before I have to call in my old man for help. Your advice is greatly appreciated.

Check the engine compression immediately after it dies. Also, check the fuel line for kinks to too-tight tie wraps, or replace it. Could also be the gas cap isn't venting as it should. At the 10 minute mark, loosen the gas cap and retighten.
