The '74 13B twin distributors (dizzies) from the REPU definitely had points. I spent a lot of time puzzling over how to adjust them many moons ago. It sounds like somebody probably used the Pertronix or other aftermarket electronic conversion on them if the points are no longer there.

First off. No 13B came with twin dizzy. Period. Twin dizzy were available from 1968-1973 on 10A and 12A engine from R100-RX3. In 1974 mazda came out with the first 13B which a four port 13B single dizzy. The motor was available from 1974- 1978. It wasn't until 1983 that the 13B reappeared in the GSLSE RX7. As for your question about swapping to electronic ignition. Yes it possible many people have switched over. I am just curious to see a picture of your motor with a twin dizzy front cover on a 13B. |
