Thanks Jack, it was a mess when I got it at the tip. I have added wheels and extended the handle since I posted. I have checked the timing and spark plug with info from this forum.
It took ages to clean it up, tried to save the petrol tank original colour but it was too far gone, saved the cooling shroud though, it looks like the original to me.
How about the carby?, is it a 125cc unit, it has the twin lines around the top and I think this means 160cc, not sure though. Thanks for the replies Jack
