advance/retard ignition timing

[mina_nuka]

Same Ignition Timing (10BTDC) from idle to 4kRPM... Sign ba to ng Stuck-up na Mechanical Advancer? Dapat bang mag advance ang Timing mark pag tumataas ang rev ng makina?

• Idle (900rpm) 10BTDC
  4000rpm 10BTDC
  Vacuum Advancer Removed & plugged
  EE100 Corolla
  2e Engine
  1300cc
  12 valve
  CDI type distributor

TIA!
