Just been out for another tinker ... tried removing the air filter completely and it does run much better... still not at full power but still better than with it in... even with the engine running replacing the air filter causes the revs to drop...
so a new filter is on the cards as step one.

Is there a crankcase breather and has it been blocked/buckled by this ?

dunno - I'm engine illiterate unfortunately - no idea what a crankcase is never mind a crankcase "breather"
It's a vertical pipe out of which oil will spill if you hold the engine upside down. Sometimes it uses the oil level dip. Pressure building up in the crankcase is relieved through it otherwise the engine almost grinds to a halt as it cannot work against this pressure.
Surely it's more about reducing oil leaks caused by elevated crankcase pressure?
Our mower was repaired recently (cable problem) but when it came back, they had fitted a tap to the fuel line, since the ball valve in the float chamber had jammed and fuel had continued to flow into the bore. I suspect it jammed because they turned the thing to some weird angle (althogh they said "it sometimes does that") - so it might be worth checking that your float is doing the job i.e not allowing a surplus of fuel - which may tie up with your findings so far...
