74 2.0 D-Jet
Heading to the garage now to start the install and my main, unresolved-in-my-brain question is if i need to hook up the vacuum line that is on my current stock distributor, on the 123. |

D-Jet is open-loop; there is zero feedback from the engine about the actual mixture that is achieved.
Many of the D-Jet cars used vacuum advance and retard both. It makes sense that you could use either one on a 123 distributor. I do agree that the basics need to be re-confirmed. Double check the timing marks on the fan against the flywheel. --DD |

I'll leave my post unedited...it is open loop...it is a hard mapped injection system with no sensor feedback to adjust the mixture. |
