Under all of the pack rat mess, once the many pounds of organic matter was peeled off with a combination of power washer and a screw driver, the original hurricane 6 cylinder engine still turned over. Drained the oil, replaced it, replaced the plugs after spaying some lube in, replaced plug wires, had a buddy rig up a little circuit on a 12v battery, and worked on it a few times and got spark then ignition in the engine. Pretty fun getting that engine to fire for the first time since 1978.
