White smoke can also = coolant. I dont think thats the problem thoughflatthump said:A simple search will yield results. White smoke =water
Black smoke = fuel
Blue smoke = oil.
Im not sure why it smells like its burning though. It should smell a little 'sweet'.
How long does smoke come out of the pipe? If it does happen, it should happen only for a second or two right when you start her up.
