Yup - It fails the classic external spark plug test - use a spare  
plug, ground it against the engine and look for the spark. It's dark  
now so I repeated and discovered one of the leads was loose. It helped  
when I tightened that connector up (with pliers) but still no spark  
until about 2000 rpm. At least I'm onto something; I'll have to check  
a number of connections to make sure they're tight, and maybe replace  
the sparkplug cap.

Yes, sometimes talking about a problem leads to the solution...
