Thanks guys. You wouldn't believe it with the Victa commando in the photo. It belonged to a family members late father. It had supposedly been in the garden shed for 5 years without starting. They gave it to me.
I just cleaned the mower with WD-40 garden equipment cleaner , I cleaned the fuel tank of its fuel, changed the spark plug, (old plug actually lstill ooked pretty good) topped up with 2 stroke and it literally started the 3rd pull and from my eyes runs perfectly.
Then a few days later I didn't even change the battery that runs the Keystart, I just charged it on the car battery overnight and it started 2nd turn of the key.
Has to say something about the quality of Victa, amazing
