I gave a rotary engine class to a small group of rx7 club members in the fall of 2005 at my Mom's farm in Spokane Washington U.S.A. It was very informal, but should be informative to those enthusiasts who might want to rebuild their own engine someday. We taped the class in hopes of making a film for those in attendance, but the main tape turned up empty and blank. Something had gone wrong with the camera. On 16 March 2007 I was able to recover the missing film from the tape, and was able to complete the movie. The movie basically shows us assembling an early 13b Mazda rotary engine and discussing various issues during the build. We did not get into porting or checking clearances. This is just a video of the assembly of an old 13b 4 port in case anyone wants to see how it is done.
This is my third attempt at getting this torrent(my first) uploaded, so I hope it works this time.
