Terrified.
Technnically, slidewithstyle, it would be a 17A. The 12A is technically a 1.15 liter, simplified to 12A as it is rounded up. 1,146cc displacement to be exact. I can't remember what famous four rotor it was, but there is one of the third gens out there that has a 4 rotor based off of 12A's. I don't know how common it would be, but it is a possibility that someone has used a base of a 12A to create a three rotor.

Maybe he was talking about a 10A-based 4-rotor.
Or maybe not.
There are some "17As" running around out there. Jeff Bruce of Precision Engineering in NZ makes kits, and Hurley Rotary does (used to do?) 12A-based 3-rotors with triple SU carbs.
And yeah, there are a bunch of "23As" out there. The one you're thinking of is probably the Scoot 4-rotor.

Yeah, I remember reading a long time ago that people could buy the custom built eccentric shafts to turn your 12A's into 3 rotors from some Australian company. If I were going that route I'd go with their 13B setup, though since you can't find new 12A housings and rotors very easily at all. It would be pretty amazing to have a "17A" though.
