X12 Timing
 

Which insert gives actual 0 degrees timing would it make sense for the motor to come with -10 as factory default, or are they classing 0 as the standard timing advance

The -10 insert is an actual 30° timing.

You cannot time the X12's to 0°.

Are you sure? I was under the impression the 00(+-0) insert was 30deg, so the OOOO (-10) insert was 20deg.

ahhh atleast my question was valid was a little worried that 0 was 0 but then why would you run -10
