Some of the smaller Lister engines had individual injection pumps (one per cylinder) inside the engine casting. With any leak this gradually filled the sump to the extent that the engine could become self charging and runaway. The only cure being to suffocate it with a pair of engineers heavy duty underpants up the air intake. I'm not sure but I suspect the FR injector pump is external to the crankcase. I was wondering if your sump could be filling with diesel, or even water but it sounds like you are safe from both those woes. You mention the crisp throttle response which, coupled of course with the characteristic turbine smoothness, is the hallmark of the green motive power units lovingly crafted by countryfolk resident near the southernmost escarpment of the Cotswolds. In former times. Beeky
