Thought I had a service manual for this engine, but it was for another one instead. How do I test the coils and plug wires on this thing? Top cylinder has compression, and is getting fuel, but not firing at all. I put new plugs in, and I can see that that one is still shiny clean.

If I do have a dead coil, should I replace them all? This engine has seen a lot of use, and I've never really had to do anything to it but new plugs every now and then, and gearbox oil changes.
