Hi
The engine will be a bit smokey especially when cold, excess fuel from starting builds up in the exhaust and manifold which does not help.
A number of things can be done to help reduce smoking, drain any excess oil that has collected in the crankcase as this will be drawn up by the two stroke ( plug in centre of crank case base )clean the gauze filter next to the oil filter , this is the crankcase breather if blocked adds to pressure and smoking. oil can also collect in the reed valve chamber which is below the air intake strangler take this off clean it in diesel and replace.
My Draytons will start with no wick from cold after a few turns on really cold days I heve replaced wicks with a glow plug which I obtained from Neil Jarrett I believe they are a citroen part. J.W. Stennett of Ipswich had a box full of cartridges the last time I was there. Hope this helps.
