There were early karts that were truly hard to manage with even a stock Mac '91. On the other hand, the Darts, Bug Wasps and their kin, Foxes, Go Kart 800's and 1200's and some others from about '61 that will easily handle even dual Mac '91's. We will have Darts and my '63 n1ke repop at Tucson in two weeks that all handle any of the good running later engines. You have to look at chassis design rather than the year of the kart. Ted
