Thanks for the quick reply, Bob.

Battery is new, but I had considered the electrical system. I bought a tool that plugs into the cigarette lighter and gives an L.C.D. readout of the system's voltage, both while running/charging, and when the engine's off, as well -- i.e., 14.3v while running, and 12.8v with the key off. Those readings would appear to be in the normal range, I think.

I don't suspect fuel delivery as the cause, because I can always smell fuel after cranking. (In fact, once last winter there was enough fuel in the exhaust system to cause it to ignite and backfire, with that explosion puffing a nearly-new muffler out in the process. And, as I mentioned in the original post, fuel pump, filter and CPI all are new (replaced within the past few months).

The puzzle continues. Thanks for your input.
