Greetings,
On the distrutor of this car there is a vaccuum advance and retard. The diaphram for the retard portion is shot and so is the switchover valve which controls when the vacuum is applied to the retard portion. Anyway so I got rid of the whole retard portion by plugging the vacuum lines (the red lines on the diagram are the ones that I plugged). Then I noticed that same hose also goes to the air shut off valve (which I don't know where it is, all I can see is a broken hose hanging off the back of the air pump). My question is if I eliminated the red line in the diagram below will that cause any problems or just raise the emission a little bit.

Some of the folks here have mentioned if I eliminate the retard portion of the distributor it will make my car run a bit better. However I didn't know that the air pump was hooked to the same line.

If I am not beeing clear please let me know. Thanks.
