Thanks. I saw this when putting the box back on. I'm not sure what's wrong with the mower. Again it was running fine, then just stopped. Attempts at starting it, and it sounds a little funny to me when I pull the starting line. I hear a loud 'pop', but it doesn't sound the same as when it was working fine. I'm attaching a video I took, but I'm not sure the audio captures the 'pop' all that well.[video]https://goo.gl/photos/mM3hVJqH2UteCyPE9[/video]

Is it possible that you picked up some water/ethanol mix in the carb, and it can't quite run on it. it sounds like it is attempting to start, but just can't ignite the fuel. Also I can't tell what spark plug is in it. It just looks longer than the stander j19lm or b2lm I am used to seeing.
Regarding the fuel, it was fresh gas, but contains ethanol. I was able to get it started, and it ran fine. Stopped it after running for a couple minutes. Started back up again 1-2 pulls. Started heading down hill and it died, can't start it again. The plug in it was J8C. I had a shorter plug, think it was CJ8 just put it in. Still can't start again. I've been trying to manually close the "throttle body" or whatever the brass flap is on the carb thinking that's the choke.
I got it to start a couple times, but died with the same issue. Would I be able to start it with a dropped push rod? I will need to read up on the push rod procedure before I begin. It's a learning experience for me.
It doesn't look like that much work to pull the valve cover off and on again, with a sealant. Just a little hesitant to do so. Would it have started and run fine for a few minutes with a bent pushrod?
The video is the reference I'm using for a different mower. I assume that the two "threaded rods with nuts" you see with the cover off are the push rods.

Ok, thanks for the clarification. Anybody have a suggested set of tasks I should preform to troubleshoot the mower given that it can start and run infrequently? I looked at the owners manual but I think I've looked at the basics like changing the plug.
