has anyone had this problem? its keeping me from passing smog
so yeah the problem again is that the degree on the timing going from idle to 2500 rpms isnt changing. whats the problem?
Re-read your post.
vacuum advance line is the rubber tube leading from the distributor, to the carburetor. It may go into a "tee" before getting to the carb.
The stock distributor comes with tight springs, on the advance plate.
While you can get lighter springs, (Mr.Gasket #925D) they aren't legal for "on-road use".
Again, your on board computer (Behind glove box) may not be calling for advance at 2500 rpms.
These old computers, & emissions systems can get screwy after years of neglect.( there is an indicator, somewhere under the dash if it hasn't been disabled. It's supposed to tell you when emissions service is required.)
John Nutter's fix for this, should be passed into law!
