I have one I bought in 1988 or 1989 with 20 hrs on it, can't remember. I think it has a B&S engine. I don't work on it so I don't keep up. My question to you is this. It recently died according to my repair person who is very reputable,
It was what ever goes through the engine which I think was the shaft had worn the hole it goes into out causing the mower to leak oil and you know the rest.

I wanted to sell it for whatever but I have no clue what it is worth or fair to ask for. I am not going to give it away because I do know for the right person who works on these can invest a little time and money and they have a work horse. But for the sake of parts can you guide me on what a fair price is.
