Erratic Timing

AJ/FormS said
That long looper does nothing to probably well past 3000. If you map out your timing on a graph at every 400 rpm intervals you will see exactly when it starts/quits, and how much it contribute which is seldom more than 4*. Fast curves are not always the answer. Getting your your WOT power-timing sorted is job #1 . Then you do whatever you can for other conditions.

Thanks! That seems pretty clear. I'll have to look more into what curve is right for my engine, but I'm not spending much time past 4k anyway, so it doesn't make much sense to keep a spring that won't really do anything.

1 degree on the lite means nothing, less than nothing to the engine, unless it is the one degree the initiates detonation. But that is easy to resolve,lol.

Haha that's what I'm worried about! I guess I'll just set it at 33* and feel safe.
