The karts look like he would take one engine off the twin to run on the single, and when running the enduro, put it on for one twin class and maybe take it off for a single class again. I thought the kart with the twin tanks may have been an early Margay model, like a Cheetah that my brother had, but with them being in Ohio I don't think they sold that far east back then. They were old karts but the pipes on them I'm pretty sure were Hartman Blimp pipes. I ran those of the MACs I ran and the LMR I ran in stock heavy. They are much newer than the chassis were. It was definitely set up for the sit up class of enduros with the two 3 gallon tanks. Being as they were in Ohio, the guy could have run at least two classes at Mid-Ohio, and had a pretty easy drive to Charlotte, Talladega, Road America in Wisconsin, and on down to Daytona for Kart week. My late younger brother took a job with Wheel Horse Lawn Products right out of tech school as a service rep for them. Once he was there for a little bit, he realized he could work in racing enduros at most of the better tracks into his work route. He was already racing Sprint karts before he moved down there, and I was also by 1978 and '79. When he got settled, he bought a full blown lay down Margay enduro set up from a local hot shoe that he got to know pretty well when he still lived here. One year over Christmas he called me and offered me a ride in one of the 4 classes he was set up to run at Daytona that year with the one kart and three different engines that he had built up. I was working for my Father-in-law at the time, around '79 or '80, and we were just getting a automotive machine shop and torque converter rebuilding business off the ground, and the old S.O.B. would not let me off to go!! That is one of my biggest regrets in my life !! I should have just quit, went down and raced, and then begged for my job back when I got home!! After my brother passed away in 2012, I brought all his vintage motorcycles home, and he still had all the kart stuff which was a Margay Panther-X and the Margay enduro with tons of spares and engines. I just didn't have any room for all of it, and had been out of it for so long, so gave the enduro stuff back to the guy he bought it from because they were pretty good friends even up to the time my brother passed away. I gave the sprint kart stuff to my nephew hoping his young boys might take an interest in it , but they never did so after shopping the stuff around they went to the same guy I gave the enduro stuff to for a nice price and everyone was happy. If I could find some one dumb enough to make a kart available and do all the work, I would still like to drive one today. I would just need a crane to help me in and out of the thing each race!! It was a lot of fun on pavement or dirt, with dirt being my favorite and what I did best at.
