Bought my first 40, she's a 12/78. Not a lot of great history from the PO except that the previous owner to him used it in Montana for hunting. I think I made a decent buy although when I got it home I found gas in the oil. There wasn't any I could see when I did the walk around so I'm hoping its a new issue. I replaced the oil and filter and ran it enough to get it into the garage. I'm starting by replacing fuel pump, lines, and returned to factory by removing and replacing the weber carb set up. While its apart I think I'll go ahead and base line it with new plugs, wires, coolant hoses, belts and whatever else I find while I'm in there. Water pump, thermostat, fan clutch, what else?
