Thanks guys,
Details below, although it doesn't offer the brand of engine, and it comes installed already. I went for the 50cc two stroke, hoping more zing with less problems. Although i can imagine it may attract more attention with the high revs and all that pinging.

Thanks Graucho, will use that maintenance site. Am pretty good with mechanics and the supplier offers all spares by delivery.
I've heard many variations in oil/fuel mix for two stroke - I don't suppose you can shed any light on this, without contradicting eachother!! hehe. Otherwise \i'll do what it says on the pack. Any particular brand of oil that is better than the next? That will prolong the life of my two wheeled lawnmower!
