    Reading your story again, I don’t see any mention of having checked the ignition system. Your statement about sputtering and dies, then pulling it 15 pulls when warm is the classic symptom of bad coils. Unless they have already been replaced, ALL 1956 Johnsons have bad (cracked) coils.

    The thing is it has the newer black coils that are not cracked. I believe a tune up was done 30 years ago but I do not know the extensiveness.
