Yes, I did mean the all around engine experience. As far as running them, once broken in (and they have very explicit instructions for this, down to the actual rpm and # of minutes to run and cool down), they are like that Ronco rotiserie. Just set and forget it! In five years I haven't had to touch the needle valve, and I'm not exagerrating. I wish others could make an engine like this.
The designer, Dub Jett is well known and a former world champion in speed competition and they do make special engines for speed, pylon and the like as well as great sport engines. They compete with Nelsons, Edmunds, Cylclons and a lot of limited production engines from specialty shops. Check out this website to see some pictures and info about the competitors engines as well as a history of pylon engines. Very cool stuff for engine nuts!
