RE: What the Heck happened to Norvell?
Norvel is no more. Das ist kaputski. The AP .061 that Tower carries is an almost direct copy of the pre-revlite Norvel. They're not quite the quality, but mine at least starts and runs very well. It took a while to break in and become reliable, though...it'll haul my 18oz Q-Tee almost vertical. The throttle response is very good and it idles well too. I'm getting roughly 18K with a Graupner 6x3 and Sig 1/2A fuel...and a Hypercolor turbohead with an OS P8 turbo plug.
