In 1964 we ran enduros at Mid Ohio. The Ruttmans showed up with a Parilla on a rear kart. That thing was a rocket and went by the little 100 cc Macs like we were turtles. 2 or 3 laps later it was sitting on the side of the track locked up due to not enough cooling. Later on I remember some guys experimenting with trying to elevate the mounting height so it would get more air, which seemed to work till they then threw chains due to the much longer chain they had to run.Then the sidewinders came out in 69 or so I think and that solved the cooling probs with the Foreign engines and also obsoleted most of the rear karts.
