I have a 42" riding mower. It has a briggs & stratton engine. At the end of last year, I had some issues with it not wanting to start after it had warmed up. So if I mowed my back yard, turned it off to move it to the front, it wouldn't start.

Last weekend I got it out to do the spring time maintenance. Now it dies after starting.

This weekend I replaced the solenoid, the battery and the gas. I also took the carbeurator off and cleaned it real good, though it wasn't dirty.

I changed the spark plug last year and it's clean. I changed the fuel filter last year as well when I first started having some issues.

Here's a video I took yesterday. I sprayed some engine starter fluid just before recording the video. That's what helped it turn over the first time. After that, nothing. Any ideas? Thanks for your help!
