A friend had his grand daughter in an asphalt sprint kart, Briggs World Formula, very successful.
The WF he had was one of those "One of a Thousand" motors where everything in it was perfectly machined right out of the box. That motor won 3 Duffys with Red at the wheel. IKF National events. He needed to borrow some fuel one Sunday for that WF, I handed him the Unocal 91 that I used. "I dunno, this motor likes the 89." :lol:
