My 22” Craftsman self propelled mower will run for 2 seconds then shut off. I changed the gas in case the gas was bad. Once it kept running after putting gas directly in the carb. It still did the same thing after that, would not keep running.

Since you have a vague question and didn't supply a model number, I'll give a vague answer: you have a fuel delivery issue. These do not have a fuel pump, feed by gravity; so look for a clog in fuel line or more likely a carburetor jet.
