My first big win Was with a left-hand drive McCullough, on the left-hand side of the kart. Rivers track, Herndon California, 1969. I have a friend in California who still has a kart with the engine on the left-hand side, he set up for years. It's really fast. Not because of of left-hand drive, but it doesn't suffer from it either.Just curious..... I’ve heard different things from different people. What is th3 difference in a lefthand drive kart? On a sprint track, aI would think, as long as it scales out good, it doesn’t matter......Am I wrong?
