What Is 1:100 Ratio of Fuel Mix for a Two-Stroke Outboard Motor?

Since two-stroke engines lack a proper lubrication system, the oil present in the incoming air/fuel mixture lubricates all of the moving parts. If the incoming mixture has too little oil, the parts wear much faster, and engine damage is likely to occur. If the mixture has too much oil, the spark plugs can be blackened from the excess oil, and the engine runs very roughly while producing a lot of smoke.
