RE: First OS Wankel Engine manual (Side Inlet Port)
Radial Power is correct. The engine listed in the OS manufacturing gallery is the same with the engine on the photo I posted. It couldn't be different:
OS has manufactured 3 types of Wankel. One, the first, was the one you see in the photos, manufactured from 1970 till 1981. Next was the PI Type I, which was manufactured from 1981 till 2007 and the third one, the last generation, is the PI Type II, manufactured from 2007, which continues to be manufactured.
However, the manual I want is for the first one. Anyways, I communicated with OS Japan and they sent it to me!
