I have seen many of these around here in Northern MN. Most are in my shop. Love these and keep them tuned up and running sweet. Sometimes at the local lake "Fish Lake", people stop by to say hi. "WOW, that is an old motor......its runs so nice." These were born when I was. They are 63 years old. I can sell a completely tuned up, in presentable appearance, with the correct pressure type tank, with a 1 year warranty, using Amsoil Saber 100:1 pre mix oil, but mixed at 64:1 and non oxy high octane fuel.......FOR........5 TO 6 HUNDRED BUCKS. Yours is far from there, but check compression and I can give you a rough number. If less than 65 psi per cylinder it is likely going to need major overhaul. But put a little mixed gas or WD40 in and try again. If it goes up to 75 or 80 psi, then it should be okay.....the rings and cylinders are dry. At this point its 150 dollar motor 200 if it has a decent fuel tank and fittings.
If the compression is low, it is worth about half that....likely to end up as scrap or parts. List it on eBay, and allow about 50 bucks for shipping. This looks original and might be attractive to a restorer. Properly tuned up, on a small fishing boat, like my 14' Lone Star, it will troll at least 6 hours on about 3 gallons of gas.
