when carbon burns in an insufficient supply of oxygen it produces carbon monoxide.
equation of it is 2C+ O2 --> 2CO + heat
but if the supply of oxygen is sufficient then carbon burns and makes carbon di-oxide
C + O2 --> CO2 + heat
carbon monoxide is an unstable compound so when it gets oxygen it reacts to form carbon di-oxide
2CO + O2 --> 2CO2
carbon monoxide is poisonous whereas carbon di-oxide is not so.
The reason being that monoxide forms a stable compound with blood hemoglobin and renders it useless(unable to transport oxygen), whereas di-oxide has no such affect
