Before the carb i'd go to the cat converter. Even with weak spark there are telltale signs your converter is or has taken a shit. Yes even with the lack of mileage it has. Who knows how many times someone had ran the vehicle for a few minutes, to "charge the battery". Unfortunately doing a short run (multiple times) does more damage to the engine than letting it sit there.
