Update for 9 July:

Took the carburetor apart, cleaned it all out with carb cleaner (twice). I found a very little sludge in fuel bowl. After it was cleaned, I reassembled everything and cranked it over. She is running like nothing was wrong. Drove 3 miles for test drive, no issues! I will drive farther tomorrow to ensure it is fixed.

Thanks for the help gentlemen!
