mcbrat Posted August 30, 2004 Share Posted August 30, 2004 I swapped out a 2 vac line ea71 disty for a single vac line ea81 disty. I have the vac line connected to the disty that helps it run the best, and the other is just plugged now. any body know what the best thing to do with it is...? it has some weird vac issues anyway (even before this swap) and runs rough until it warms up....

GeneralDisorder Posted August 30, 2004 Share Posted August 30, 2004 One line is for advance, and the other is for retard. I have an '80 manual that has the diagram for that disty I think.... we'll talk. GD Link to comment Share on other sites More sharing options...
mcbrat Posted August 31, 2004 Author Share Posted August 31, 2004 well, I have the '83 disty in now though.... but I noticed it pinging horribly on the way home tonight. Disty was a tooth off, so I fixed that, and it runs much better now. hopefully it'll have a bit more power. a kid on a bike could have passed me today Link to comment Share on other sites More sharing options...
Caboobaroo Posted August 31, 2004 Share Posted August 31, 2004 yes what GD said is right. Here is kinda the scoop on it though. When you swap to a newer style of disty onto an EA71, you need to plug the vacuum retard line which is the lower one connected to the vacuum module on the front of the intake right under the carb. The other line is for the vacuum advance which gets connected to the disty. Link to comment Share on other sites More sharing options...

And as I recall, the retard line only works durring cold running... GD Link to comment Share on other sites More sharing options...
mcbrat Posted August 31, 2004 Author Share Posted August 31, 2004 amazing what one tooth can do runs much better, and lots better power now. my wagon is a happy camper again Link to comment Share on other sites More sharing options...
