On this subject.

Is there someone with knowledge about modifying the mechanical advance on A series dizzy.

Haven't found anything in the tech section.

What to look for?
Available Modifications options?

This is a interesting link: http://www.gofastforless.com/ignition/advance.htm

Just wondering, because someone told me that I would need to start looking at modifying my mechanical advance curve after the GX head and SU's are installed on the A14 to get the most out of the setup.

This leads me to one big problem, what is the signs that this needs to be done. Pinging comes to mind, what else?
I'm from SA, hell I even wonder if there is some tuning shop that can do something like that, or do I start to get the info on a DIY method.

I'm thinking of taking it to a Dyno shop and ask them to run it and give me some info and advise on the timing and take it from there.
