I use a Husqvarna riding mower to do most of my yard but use a twenty year old Echo self propelled mower to do the trimming. For many years, I used the Echo to do the entire lawn which is of considerable size (.5 acre+). Due to the slope of the front lawn and the ridiculous price of mowers with pressurized oil systems (at the time), I opted for a two stroke engine. The Echo has a 140 cc engine and with factory settings, makes 4.5 h.p. at 2800 rpm. Power is fine at that setting but the self propulsion was a bit too slow for me. I adjusted the governor to give me more engine rpm to help pick up the speed. Now I have a throttle range of 1600 to 4500 rpm which gives the mower much more speed and power. Once the engine is warmed up, there's very little, if any, smoke from the exhaust.
Two strokes are indeed a wonderful engine design. Simplicity, flexible power, light weight and reliability.... What more could one really ask for? How about resuming modern two stroke manufacturing and technology development for OPE applications? After all, Bombardier's Evinrude/Johnson outboards and Skidoo snow machines use very advanced fuel injected two cycle engines that easily out-perform equivalent four stroke engines of equal displacement.
