How much ignition retard and fuel enrichment should na engines use ?
I tried 10 degree ignition retard and 40% fuel enrichment, is this adjustment ok or because of this is na engine we don't need ignition retard and fuel enrichment ?

Thanks

You shouldn't have to use any of these things on an NA engine as you are not trying to build boost.
