Hi all,
I have been advised by my mower repairer that the Two-Stroke Victa Tornado Self-Propelled Mower that I bought 11 months ago has a scored piston. I was told that it was most likely due to insufficient oil in the fuel. I have worked as a gardener for five years now and admit that this problem occurred to me once (a few months ago) as I must have forgotten to add oil to one of my tins. However, ever since I been extremely careful with ensuring the correct amount of oil in my mix and have only used Shindaiwa oil. I can't understand how it could happen again so soon and despite me being ULTRA careful. Can anyone advise me whether there are other possible causes? (I noticed that before the mower stopped running properly, it was over-revving, and so I ran it at about a 1/3 throttle speed). Thank you
