I have just dug my wre 125 out the shed which I dumped in there because of an electrical problem 6 months ago. I fitted a new stator and flywheel and I had a nice bright spark so problem fixed and it kicked up on the fourth kick it was smokey as hell but running. The bike is running pre mix but I forgot to drain the carb when I last put the bike away so I drained the carb and the petrol that came out was green but the premix in the tank is still a nice red colour. The problem I have now is it keeps fowling the plug with green oiley petrol so Im going to clean the carb out tomorrow, do you think the premix thats still in the tank would still be ok to use thanks.
