That means it was made on 19 September 2001, so I don't know why the coil looks like an old one to me. One possibility is that it doesn't have the original air cowl. Does the starter cord pull up vertically or horizontally, sparker? Pre-Magnatron vertical crankshaft engines had vertical pull starters. (So did the first few years of Magnatron ones). If the air cowl is correct, I'm unfamiliar with the ignition coil it has - which isn't important but may be interesting.
Post-Edit: The coil is a Magnetron, as noted in a previous post-edit. And I should have known the engine had a conventional recoil starter, not a vertical pull. For normal recoil, the model number ends in 2. For vertical pull, it ends in 8.
Meanwhile I'm glad that is sorted out. It is nothing unusual with second-hand mowers, sparker, for the problems to be due to the tenant's improvements. It is one of the things that keeps us on our toes.
