I would imagine that the sugar in the fuel would form giant lumpy carbon
deposits on the exhaust valves that would keep them from closing and
therefore making compression. That's what happened to our 1949 Fargo
flatbed with flathead six back when we were hippies. :-)
The guys we lent it to filled it with diesel, maybe because it was so slow,
and sure enough, we had to go and get it ourselves cause it wouldn't run
anymore!
Peace and love, Jake
