Oh Tilly2, I didn't know this thread had been on yesterday, anyway It made me laugh as we have had our petrol lawnmower for the past 15 years, we have been having this problem lately trying to get the thing started he has so many pulls then it's my turn, honestly the neighbours must see us and get a laugh, what we now do is have a spare spark plug heat it first, put it in and it usually goes after a couple of pulls, it is a great lawnmower when it gets going too.
