Which of these two diagrams is correct...the top or bottom one?
The difference is the hoses at the dizzy vacuum can...they cannot both be right. [NOTE: I deleted the incorrect diagram originally posted...the diagram remaining is the correct configuration] Attached image(s) |

I have tried both on a 76 2.0 liter.
For emmisions, when you have the retard hose connected, it pulls that advance back very quick... That is good for emmisions, but it sucks for shifting...it snaps you out of advance to quickly. We eded up pulling the retard hose off the distributor Leave the port on the distributor open so it does not create a vacuum and never allows the advance to come back. We then left the hose attached to the throttle body, and plugged the end of the hose to eliminate the vacuum leak. Our 73 1.8 only has one port on the throttle body 72 1.7 has only one port on the throttle body 76 2.0 liter has two ports, but we are configured as above. We tried it both ways and found that the rapid reduction in advance created a very poor idle condition when warm. Rich |
