Hi Grumpy,

The guy returned the mower to me yesterday stating it would not start. He was quite polite about it which was good as he understood I do this as a hobby.
He showed me oil which was pouring out the exhaust. This immediately made me think the mower had been turned over to wash it. He assured me it hadn�t however I wanted to check if there was any other possible way this could happen without turning the mower over.
I quickly proceeded to wash the cylinder out with petrol and pulled the rope a number of times. I cleaned the plug and it went on the third pull. After a minute or so the smoke cleared and it proceeded to run as normal missing the occasional shot.
For good measure I also thoroughly cleaned the carby and replaced the diaphragm as I am not a fan of re-using them.
It now looks to be running spot on again.
I don�t suppose you have any additional thoughts?
Thank you as always.
Peter
