Bagong linis din distributor cap and rotor using sandpaper and cotton cloth. Bago fuel and air filter. Na-timpla na din gas-air mixture. Pero rough idling pa din siya. Ano pa kaya sanhi nun? Need help, mga fellow tsikoteers. Thanks!

your 2E has an ignition coil in the distributor. over time, the coil insulation gets breached by heat and constant exposure to high voltage. try tuning in to AM on your radio. if you hear static proportional to the engine speed, the coil insulation had been breached and needs to be replaced
