Street Demon tuning experience

This is where ign tuning comes in. In particular vac adv connected to manifold vacuum. Ideally an adj VA unit.

As an example: init timing is 12*; then there is the centri curve in the dist. Vac adv adds 23* at idle to give you 35*. You can have any combination that gets you where you want to be. Under the load, the VA drops away.
