    It’s deffinitly a spark plug issue… I can’t find the right spark plugs anywhere near me Champion J6J is what is recommended, J6C is a newer replacement , I cant find these either.

    I went to autozone and advance auto and picked up 2 different pair of plugs that were cross referenced.. autolites and NGKs… I gapped the NGKs to what’s recommended at .020 and could maybe get a spark once every ten pulls…. with that I got the engine to cough… but these are obviously not the right plugs or maybe I need to gap them differently?

    I originally had some AC delco plugs that put out a ton of spark but are not the right size at all
