I'm not posting here in an effort to sell any parts here but would like some help with pricing as in real world versus ebay pricing. I see some stuff on ebay and the prices are sometimes stunning. Would I be out of line to ask for 2/3 of ebay prices or would 1/2 be more realistic? The one tractor has been setting about a decade under a carport. Today I removed the valve cover to check for a stuck valve (It was so clean that I have to think it might have a rebuilt head). I filed the point in the magneto and put fuel to the carb and it fired right up without smoke and seems to run great, the oil pump didn't need primed, the valve train is oiling. What would be the approx value of this engine? I'm in NE Indiana.
