I've changed the spark plus, fuel filter, and added new fuel. The engine will crank once I put fuel or starter fluid in the air filter, then die once it is used. I took off the fuel lines to see if fuel flowed, and it did. I also sprayed carb cleaner in it just to see if it was gunked up. It sounds very good when its running which means to me that the engine is in good shape, and it's just not getting any fuel to flow to it. Any suggestions would be great. Thanks!

I actually fixed my mower last week. The issue was the "float pin" in the carburetor. I took the bolt out if the bottom of the carburetor and pulled the bowl off. There is a white U-shaped piece with a pin in it. I pulled the pin out and dropped the U-shape piece down, and cleaned off the pin with carb cleaner. Once I put everything back together, I sprayed some starter fluid into the air cleaner area then it started and continued to run. Hope this info helps someone else out.
