[QUOTE="Pappy, post: 411493, member: 3278"] "Sputtered and died" is not a good enough description to go on. What RPM were you normally running at when this happened? On plane? Idle? Did the engine shut down as if you turned off the key so to speak? Hint here is that a fuel issue will be less abrupt than ignition issues. If you try and start the engine immediately after one of these shut downs what happens? If it will not do anything no matter what you try then later starts if nothing ever happened that would be good information as well. Fill in the gaps here and we can start on it. I would not remove a plug and hold it against the block by the way. Plug wires are short enough that the spark may catch the fuel blowing out of the cylinder and light it off. Inline spark checker is the easiest followed by mechanical spark checker. [/QUOTE]
