Hello! I've got a carbed -4 2.0l and have the 123 distributor with 16 curves.
When engine was set up it was set using standard timing for these cars (Which I think is 10 to 17?) Can't remember off the top of my head but whatever the mark on the fan is at) Which setting on the distributor should I use? I cant find any solid sources for this distributor. It was at B when I got it - and has been left at that since.  And while I'm asking all these questions, does anyone know what DEGREES NEGATIVE VACUUM !!!!! is and if I need one of those settings or not - it was set on one so I assume I do but idk. I do not know anything about timing, but want to learn! |
