...And what does the vacuum advance do?
I've been wondering this for a while. This summer, I found a NOS
vacuum advance unit for my 45DE dizzy. I figured that, paired with my
electronic ignition, I ought to get some good results. I checked for
leaks and found none, then put the unit in the car.
After driving the car for a while, I realized that this unit was
costing my car power! Even though it was hooked up to factory specs
and there were no air leaks, it still caused my car to suck. My theory
was the it was an emissions-related change that made the car run
cleaner, but with less guts.
So, since we've got so many great experts on all things automotive, I
was hoping to get a dissertation from one of you about what a vacuum
advance does, how it affects car performance, and why they were fitted
to the car.
And of course, I'll be willing to listen to arguments as to why I
should hook mine back up... 8-)
Thanks in advance for any info...
