I noticed that dogshome has used the RCEXL ignition unit.
The instruction of this unit says that the timing should be set at about 28degrees BTDC.
The datasheet from this unit says the unit advances a minimum of 4 degrees and 10 degrees at 2000rpm till 35degrees at 4000rpm.

Question: Shouldn't the timing be set at 0 degrees because the CDI does the advancing? I know the manual says to set 28degrees pre ignition but i'm concerned if the pre ignition isn't way to much if the unit is adding 4 - 35 degrees pre ignition.
