Just to avoid confusion... I'm not flacoman (who also had difficulty with primer bulb failures)- but still had to recently replace my FS40 primer bulb due to cracking. The engine seemed to run just dandy up to this point. However, now the darn engine won't seem to run for more than 5 seconds or so without sprutterin' and dying. Does this symptom clue any of you guys in to what my underlying problem might be?
