As usual, I see it’s the lawyers’ fault!
If you’d actually read any of John Deakin’s articles (I have no idea who “Deacon” is), you’d know that the primary impediment to running LOP is the quality of stock manufactured engines. They rarely have induction/injection systems that result in all cylinders reaching peak on the lean curve at the same point during the leaning process. That means they ‘run rough’ (which is
PR department-speak for “vibration due to different cylinders putting out different power”) nearing the lean end of the lean curve.
When lawyers build engines, they do it properly. Ask George Braly.
