The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

The piston ends its downstroke and begins moving upward, compressing the air/fuel mix until combustion happens and the whole cycle begins anew. This means that the high torque efficiency of the ...

Anyone who appreciates simplicity of design and efficiency of operation has to like small two-stroke-cycle engines that power construction tools such as cut-off saws, rammers and breakers. Producing ...

It’s been a while since two-stroke engines went the way of the dinosaurs, with them being considered too inefficient, noisy, and emission-heavy for the 21st century. It is widely believed that the ...

Have you ever woken up in the middle of the night worried that you have never, ever changed the oil on your two-stroke lawnmower? Well, you can relax. A two-stroke oil change is like a left-handed ...
