Since it didnt sputter or start when you put fuel down the carb throat it is electrical related. Since you had ongoing problems it could be an actual problem not related to the things you changed. I would still suspect the timing belt, coil and distributor related pieces. Since you experienced a period of low power I would look real close at the timing gear.

On second thought the carburator could have a problem and maybe should be taken apart and cleaned.
