Hmm.. dami mo na rin pala napagawa. Anyway start tayo basics ulit for isolation lang

The way i see it based lang sa description mo its possible na electrical issue or fuel related problem yan. Try mo muna the following

1) Check the high tension wires baka may isa dyan may tama na. A tester will do ang replace all na kung hindi pa napapalitan
2) Double check the distributor cap baka pud pud na
3) Palagyan mo na ng grounding kit kahit i DIY mo na. I highly recommend you have this done
4) Check the fuel filter baka madumi na
5) Do you use an air filter for the carb? Kapag wala that will cause na pwede magbara sa passages yung dumi. Kung meron naman and you already used the car for 20,000 + KMS then its due for replacement na
6) When was the last time nagpalinis ka ng gas tank? This is optional naman kung wala ka napapansin na nakargahan ka ng may halong tubig

After doing this and hindi pa rin ok lets see kung ano pa pwede gawin later
