2 cycle lawn mower burning too much gas??

I recently bought a used 2 cycle lawn mower. It works ok but it seems like its burning an awful lot of gasoline, compared to the 4 stroke lawn mower I used in the past.

Is this typical of 2 cycle mowers or perhaps the carb needs an adjustment so that the engine doesnt go as fast??

Hello: George

Higher fuel consumption in a 2 cycle engine is normal. The engine fires on every stroke of the pistion to produce the same power of a 4 stroke.

There should not be an overly rich fuel mixture as long as the smoke is not black in color, the engine is running fine and the oil to fuel mix is correct.
