OK another vacuum hose thread.
Just got my car running again after 4 months down, and during this time I got in on the 123 distributor GB. My engine is a 2056 with the 2.0 FI and two port throttle body. I have the dizzy set on position #1 which is used for the vacuum advance. and this is the port I have hooked up. (green arrow - A ) and I have blocked off port B  It did run okay but not real enthusiastic, which makes me think I hooked up the wrong vac port on the throttle body. Is port B the advance port? Previously it had the stock dizzy with both vacuum lines hooked up. right now it is just static timed at 5 deg btdc using the led built into the 123 dizzy. what benefits are there to using the vacuum port for advance VS using the retard port and the corresponding setting in the dizzy? Fortunately I can access the dip switch in the dizzy without removing it. (I think) Hopefully Beat Navy will wade in on this subject since I think our engines are set up similar. |
