Hi yep those old B&S 23's run nice and have power & torque I have a 1949 Economy Standard with a 23FB.So funny you mention the wall switch. I have a shelf in my shop where I put "interesting fixes" just to keep as memories and give a good laugh. You'll be happy to know that the wall switch made the shelf lol.
It does a B&S 23DFB. Runs like a champ too.
