Jim, you'll dig my story then, especially if you know '60s karts. My dad ran an altered in the 60s-70s so I of course was ruined from the start, lol. After bugging the s**t out of him for a year, he surprises me with what he thinks is a "go-kart". He got it from a buddy who lettered a lot of race cars from our area back then. Well it was a Rupp Dart Kart, with TWO West Bend engines, each with 2 Tillotson carbs, and, it ran on nitro. So it was really a serious race kart for a grown up, I was around 8. We fired up just one engine, and the thing was vibrating and popping and just super loud, my dad shut it off and just said, "these things are coming off right now and we're putting a lawnmower engine on it!". We both wish we had kept that kart all these years later, would be a pretty neat vintage deal. Oh and we saw McClure run his kart at our home track at the '72 Empire Nationals, just amazing.
