In the 1st container (coke bottle), the top portion is gasoline. What is the darker color on the bottom? Water (why it's dark like oil) or oil? I have attached the photo of gas that came out of the carburetor, it looks like water at the bottom, it does not look dark like in the coke bottle. (I just drained it today & I still can't get it to start). Sorry, I didn't see the message on page 2.
