While in for mot, (usual stuff, holes in chassis, rear brake discs corroded, etc) now passed, I asked my indy for thoughts on rough running. Pulls well all gears, happy up to 70 or so, but still rough. Turns out the crankshaft damper has let go. Surprised for all my years on lz I have not heard of this but live and learn. Sourcing a new one, prices seem to vary from £100 to over £300 or so. Anyone had any experience of these?
