Dizzy help
Here's some graphics using the specs from some factory service manuals.
Notice how quick the timing advances in the first stage. That's controlled by the light spring.
The spring with the long loop slows the advance above 2000 rpm.
This is true with the pre-emissions advance curves as well.
The biggest difference is the pre-CAP timing curves used more initial timing, and shorter loop on the secondary spring.
(This is for a stronger idle with slightly richer idle mix but also more CO. This is closer to what you want.)
