jp its very common for a two stroke to do that they dont burn the two stroke oil off very well until they are hot so it will chuck out a big plume of smoke when its cold,on the other hand it could be the two stoke pump allowing the oil to leak through it which it shouldnt do,does it do it more in the morning and less in the day when you have not left it standing for as long??if so then this is a good possibility the oil can leak past the veins in the oil pump and fill the crankcase partially with oil (can also foul the plug if its alot)this is very common with yamahas like the jog and bi-wiz and why ect although i have never heard of a peugeot doing that its not to rule it out,so try another two stroke pump on it and see what happens ok good luck mate ,adam
