Distributor springs
Reading the graph, we think that reducing the advance to 18* will result in something like sketched here:
But what actually happens is it starts advancing earlier and ends up more like this:
(using orange and purple springs for example.)
Preload can be regained by bending the spring perches out.. But we want to limit the number of times we bend them back and forth!
*PS. Ignore that "factory standard v8" nonsense. No such thing I've seen.
Right. Same challenge many of us have had; The advance adjustment cuts off the top of the curve, and worse, it also reduces initial the preload.
