I have several of these, one a horrible looking despicable mess, no paint on the cowling, just before I went to put that one back where it came from I thought I would have a fiddle with it, the carb had been run dry, the starter knob is a peice of fencing wire and the whole kit looks like it had been outside for at minimum 10 years.... bugger me dead it went second pull and after the initial run goes first pull, its a horrible looking machine since I am still yet to paint any of it but performs flawlessly, probably even better if I went to the 50:1 on the fuel cap over 25:1....
They are a very nice very smooth 2 stroke engine with tons of power to boot.
