Need fuel mixture for McCulloch Timber Bear chainsaw?

All chainsaws are 2-cycle engines, which means you need a fuel mixture of gas and oil. All of my chainsaws require a 2:1 mixture (2 parts unleaded regular gasoline and one part 2-cycle motor oil). Fill up a gas container to the first line with gas, add the oil, then fill it up the remainder of the fraction of gasoline.
