Thanks, I'll bear that in mind. Though I was hoping not to have to
empty the fuel tank, as that would mean changing the oil again, and
I've already changed it once... (Manual says not to tip the mower

I think you'll find that the carb and fuel tank come away as a single unit
held onto the cylinder block with just a couple of bolts. Watch out for
the linkages/springs that connects to the vane under the fan cover that
regulates the engine speed according to load.
