I began with purple and orange springs

I can't find on line the P5153446 kit instruction sheet to show the diagrams and I don't have scanner.

I have allways replaced the heavy spring with a lighter one to dial in the advance curve....this should bring the total in between 2200-2500 rpm. Leave the medium spring installed and just replace the heavy one

wouldn't be better to keep the max advance higher as posible keeping a nice initial fast curve for throttle response? I meant to prevent detonation? Or is backwards and max advance must be reached sooner ?

just learning

Faster curve should be more responsive until you get detonation then you need to slow it down some
