If I was you I would have it rebuilt, I took a turbo from a friends perkins home with me last time I went & had a shop in Topeka, Ks. put a new cartridge in it. I think the cost was $750.00 if I remember right, if you do that you'll know what you have & it's cheaper than buying new & better than taking a chance on a used one.
