The air filter should be cleaned and lightly oiled. Just enough so you can feel it, but not enough to be wet.
I think this ended up being the issue. I figured that a little bit of water would be ok but at least 0.5 oz came out of the carb float bowls when I drained them a few days ago. Per your suggestion I drained the entire tank, and then emptied out the float bowls again. Put some new gas in there stuck her on prime and she fired right up. WOOOOOOO And then she died again. So I checked the spark plugs again and I had gapped one way larger than the other one. Fixed that and she's good as new now. Rechecked the air filter too and I might have been doing the motorcycle equivalent of "Web-MDing" It was oiled lightly but not too much. Thanks for your help.

To get an idea whether the problem is fuel or ignition, you can take the spark plugs out and lay them on the top of the engine so their bodies are grounded, and then crank to see if they spark. It's not likely that a problem related to the oil you see would suddenly make both cylinders stop firing.
After I emptied the fuel and replaced it, I checked the spark again cause it was sounding like it wanted to fire but wasn't. I used your method to check spark. I had spark to both but somehow had one gapped too big. Thanks for the help.

Did this when I put the new gas in and it worked. Switched it over to ON after I had it running and it continued to work. Thank you!

Hopefully not.
When I did the spark test again I didn't see anything of the sort, so that's good news. I had a few beers while I was trying to figure out what was going and may have over-exaggerated how wet the filter was, I looked at it again today and it was okay. Thanks.

Thankfully it didn't come to this. Appreciate the info.

Thanks all!
