Lawnmower motor pickup truck

[Frank S]

I don't know why he selected a 6.5HP engine unless he did it just to prove that a small 1 cyl engine could pull the little truck, or because it only cost him 120 dollars.
He could have installed one of the V twin 24 hp engines then the little truck would have had enough power to have gone to a higher ratio chain drive probably could have made it run legal highway speeds
