From the Beginning
 

First RX-7 was purchased in 1979. Now running 1981 with Rotary Engineering four port 13B with dual Webers. Clutch is now slipping at higher rpms after last engine pull. Using same competition pressure plate and a new clutch disc with new throw-out bearing. Anyone have experience with the wrong throw-out bearing (too-thick) being the problem?
