Welcome to the 'bolt page. I think a 366 would be like any old motor that hasn't run in awhile. Do the basic things: Is it getting spark? Is it getting fuel? Are there any necessary parts missing? Can you check the timing? When you get it to turn over with the double batteries is it lugging or straining? Making bad noises? Maybe there is something wrong inside the motor? Full of oil? Inspect the points, rotor, dist. cap, plug wires. Could be a bad condenser if it's not getting spark.
Good luck.
