Who doesn't know the stunningly beautiful 4-stroke engines from Saito? For years, they have been known for their highest quality and reliability. Saito engines gained fame during the era of glow engines. Always designed as 4-stroke, they come in a black housing with a golden valve cover or simply in a silver housing. Later, modern large-displacement gasoline engines with various cylinder configurations followed, also in the typical 4-stroke design. These gasoline engines quickly became popular, being regarded from the start as powerful and reliable. Gasoline engines have a lower fuel consumption than glow engines, and the fuel is significantly cheaper. The electronic ignition allows for starting the engines without a glow plug, greatly improving user convenience compared to earlier engines. Typically, regular unleaded gasoline is used in combination with high-quality 2-stroke oil at a ratio of 15-20:1. An English-language manual is included with the engine. FA120R3.
