      Didn’t want to hyjack other thread.

      Need lift and spring tension for fisherman. Was cut off in other thread.

      How to you achieve more or less spring tension? Larger spring, smaller spring?

          I’ve never compared the two side by side but for rise I’d go with the spec for the Lightwin from the posting. Lightwin in 1940 was a 5 hp opposed twin.

          Maybe that will start a discussion 🙂

            The valve lift is 3/16" and the valve spring pressure is six ounces –
            The parts book is confusing and misleading. It shows the same parts for many models.

            . . . . . . 🙂

              Thank You!

              Yes, I thought it would likely be same as a Lightwin, just wanted actual specs for fisherman to be sure.
