15. A method of running a simple engine, comprising:
-
supplying air and fuel to a carburetor, to produce an air fuel mixture, supplying the air-fuel mixture to a cylinder, supplying additional air to the cylinder, wherein the additional air flows through a carburetor bypass air intake path and into an air-fuel mixture path and the additional air does not go through the carburetor, and igniting the fuel in the cylinder to drive the engine, wherein the simple engine includes a hand-operated valve along the carburetor bypass air intake path for controlling the flow of air through the carburetor bypass air intake path, only air passes through the valve, and adjusting the valve causes a change in the air to fuel ratio. - View Dependent Claims (16, 17)

18. A simple engine, comprising:
-
(i) a cylinder, and a spark plug in the cylinder, (ii) a carburetor, fluidly connected to the cylinder, (iii) a primary air intake path, fluidly connecting atmosphere to the carburetor (iv) an air-fuel mixture path, fluidly connecting the carburetor to the cylinder, and (v) a carburetor bypass, comprising (a) an inlet tube, fluidly connecting to the air, (b) a hand-operated valve, fluidly connected to the inlet tube, and (c) an outlet tube, fluidly connected to the air-fuel mixture path, wherein the carburetor bypass provides air to the air-fuel mixture path bypassing the carburetor, only air passes through the valve, and adjusting the valve causes a change in the air to fuel ratio. - View Dependent Claims (19, 20, 21)
