Earlier today my wife noticed a Wren inspecting the Farmall B on the trailer. Debbie said she is building a nest in the starter hole.The starter is missing. This evening I unloaded the B and pulled the cyl head. Not pretty 2 froze and busted sleeves. one piston has a sizable hole pitted on the top. The cly head likely will need valves and seats.The oil was clean no water. Not any sludge on the valve train. Probably a good engine until it rained down the exhaust? I bet the crank and block are still usable? There is some funky looking stuff in the settlement bulb. T he inside of the gas tank is suprizingly pretty clean.And right now that little Wren is hopping about on the trailer. Silly bird is wondering where the potential nesting place went.
