Hi Fellas, has anyone had an issue with petrol that has been contaminated with water ? i am having trouble with my AT 3 and when i do get it running i get alot of white / grey smoke and it wont rev very well . i noticed some kind of substance in the float bowl when i cleaned the carb out . like a globule of something and the petrol looked darker than usual ?i will try a new fuel supply in a temparary tank . any ideas. thanks.
