Skip, that's a beautiful restoration! It predates my karting years (1982 - 1989 for sprints, plus time up through 1997 in enduro lay-down's), but it and succeeding posts really bring back fond memories. I raced in NE Ohio, as far south as Port Washington, but mostly at Columbiana (my favorite) and Thompson, where we built a track.
My first races were at the Flat-Rock Speedway with the Ford Thunderbird club whose president was Ford racing's Lee Morse and included Jack Roush, who had invited me up. When I was with the FAA at Mansfield, we were right across the road from Rupp Mfg, where the Dart Kart track had been, and I later raced in what was called the Mid-States Series, arranged by the Michigan Kart Club and the Dart-Kart Speedway club at Gratten, Mid-Ohio, IRP, MIS, and a couple other places. I studied my kart racing history. That and the violin were my passions.
I only owned four karts (in succession), a Margay Expert, Margay Expert II, Margay enduro that I never raced (should have kept it) and a Proline enduro. The Expert II had an Atlas and then an LMR with vented disk (because Scott Pruett used them), and a ton of stuff like pipes, brackets, etc, that I designed and Mike Pochiro enjoyed building. I loved them all and woke up every morning driving those tracks and thinking about set-ups and mods. This really takes me back.
The last picture is not one of mine. That's a kart I aspired to, Scott Pruett's B-Stock "Formula 200" kart in which he won at Long Beach and here in Cleveland, when he turned a lap only 13 mph slower that the slowest Indy car to qualify for the 2nd (I think) Cleveland GP. I never could afford to race that class. Now I just wish I could still race karts.
BTW, my soon to be EX-friend Tom just bailed out on our arrangement to drive together to the "500" and vacating my extra ticket in the first row of the SW Vista, with a view from the entrance to turn one through the entrance to turn two. If I cannot find anyone here to share the ride and room and pay for my extra ticket, it's available. If it doesn't find a taker here, you'll probably find me standing outside the gate near the Speedway Motel site on 16th street hawking my ticket among the scalpers. Ha! My 72 years there have come to this?
