I'm pleased to say that my mower is now working.
My mechanic mate went straight to the carburettor and found that the fuel therein had gelled and there were also some crystals in there.
The jet was blocked but was soon cleaned. Upon re-assembling, it started after the second pull of the cord.
I'll charge the battery tomorrow in the hope that the key start can be used once again.
Thanks to all who contributed advice and information.
My mechanic is the owner of the
Labrador in Post #6 so I didn't even get a bill.
I do like a happy ending.
