Hi Hamzah, Good to see you after a long time. CDI Dizzy is locally engineered in Karachi. Tried to source the OEM one but it was impossible. One option was the below link but then the cost including delivery was steep.
227 1216 Ignition Distributor Spark Plug Wire Set 8mm Accel Toyota 2F 3F | eBay
Second had 3F-E distributor was available but as you know, that does not have a vacuum/mechanical advance functionality and vacuum is controlled through a sensor. So, I opted for 3F vacuum distributor upgraded to a CDI system along with a coil.
Still need to tinker a bit with advance (~7.5 BTDC) and fuel mixture, but overall performance has improved significantly.
BTW, how many km were there when you down the motor?
