I actually have a couple Lycoming IO-540s laying around and some club
props...maybe an air powered kart is at hand... j/k, I'm not Eveil
Kneivel...

I'm not looking for a sandrail... I need small single seated. I'll
scrounge for an old lawnmower engine or an old gen engine...maybe a
honda or briggs...
I'll load my pics of my plans when I complete them..

BTW, any thoughts on using the Quad parts for the go-kart?
