I've been having a serious timing problem with my 2nd gen RX7. First my Racing Beat e-shaft pulley was mismarked. Finally figured that out and swapped it for the stocker. Well, I still had to feed the thing about 10* advance to make it run right. Posted a couple times to the RX7 Club and a guy gave me a link to a page that has some good 2nd gen ignition info. This guy says he's seen two cars that appeared to have somehow slipped time. He showed how to find TDC without relying on the pulley. Well I did it and according to this method my pulley was off by about 10*. With the new mark everything is dead on. Anyone heard of such a thing?
