Well , I finally picked myself up a Jensen 5 off of Ebay . I had been wishing for one of these for sometime , and I am not disappointed . I simply cleaned it up , gave the base a fresh coat of polyurethane , worked on the sight glass a bit and added a new pulley . After running it some , I can say that I believe that this may be Jensen's finest engine . It is a typical Jensen , smooth , quiet and powerful . here are a couple of pictures .
