Does anyone know the firing order for a 4 cyl boxer two stroke? If we use a Lycoming 4 cyl as an example, the firing order is 1-3-2-4. Since a two stroke fires every time the piston approaches TDC would a 4 cyl boxer two stroke be a "Big bang" engine with cylinders 1 & 4 firing simultaneously and then alternating with cylinders 3 & 2? Has there ever been a 6 cyl boxer two stroke?
