Exhaust pressure of an air-cooled miniature internal combustion engine is used for fuel metering and fuel delivery to the engine under higher pressure than previously obtainable from muffler back-pressure in the prior art even though the back-pressure in the exhaust system is kept to near zero for maximum engine power and cooling. This is accomplished by tapping on to the engine\s exhaust stream right at and facing the exhaust port. As the engine unloads, the muffler\s exhaust is further aspirated outward by a faster-moving cooling airstream hence a furt...
For use in combination with an internal combustion engine having an exhaust port, an exhaust conduit wherein resistance to the flow of exhaust gas creates back-pressure to said engine, and an air-intake conduit containing a fuel discharge nozzle, a fuel supply and metering system relying upon exhaust pressure obtained from said exhaust port, comprising: an exhaust pressure tapping means placed in proximity to and facing toward said exhaust port, thereby resulting in higher exhaust pressure obtainable therefrom than the exhaust back-pressure existing at d...
