Putt Putt Putt Putt

This engine is one we saw last October at Boonville, Indiana. Unfortunately, I did not write down any information, or take a photo of the builder's tag. The carburetor looks to me as if it could be a Fairbanks, but I really don't know. You will notice when you play the video that this little engine is throttle governed, not hit-and-miss like most engines of this vintage. Can the readers help with the brand name?
