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. |

"Posted vacuum comes from a vacuum port that is covered by the throttle blade at idle.
As you open the throttle the vacuum reading will increase sharply and tend to hold vacuum throughout most of the RPM range. It's creating vacuum by the passage of air. The faster the air is passing the higher the value." i found that it just runs better with out using it even though i have thed-jet with vac unit. . my idle is better - been a while but i thing that i had too slow of idle with it hooked up , and i tried it every way, but dont use and and am using the curve that is ment for no vac, i think its "B" but i dont remember off the top of my head |
