I am considering a 48" Wright Stander for my next purchase. The engine options are 17 kaw., 19 kaw., 20 briggs, 23 kaw. Anyone out there with experience know which I should choose? Is 17 hp enough? Is 23 too much? I have a Sentar with a 25 kaw. Other than some carb. problems I am happy with it. I really like the design of the stander I just don't know which engine to get. Thanks in advance.
