Found that Webra .60 rod. The piston end is fatter than the crank end and it looks odd but it worked very well. And note the slot on the crank end. A good idea that seems to have worked as well. There is no slop here except that which might be expected from normal clearance. And note that it isn't brass bushed. This engine saw many, many gallons for fuel over some six years. However, that was some thirty years ago and it isn't Schneurle ported. I'm fairly certain that it never saw anything but a castor based fuel at 25% as was the norm back then. Still,,,
