I think that is what i will do then, The mower was provided with a spare engine of sorts (in parts, in a box) so as i pull it down, i will check anything over, and see if anything needs replacing.
I will also make sure to get pictures as i go, especially of the Ignition unit, its quite unusual (Crankcase magnito, inside the cream box at the front)
Hopefully I can get this one running, I dont think it would be much good to me for cutting (to much grass for a 15" to be practical) but I do like to have the collection running, and i will occasionally take them out to tackle a small patch each, then give them a good clean.
