Claims

[Scope of utility model registration request]

A throttle lever 4 is fixed to the throttle valve 2, a fast idle lever 5 is movably connected to the throttle lever 4 through an adjustment mechanism that adjusts its relative position, and a fast idle lever 5 is connected to the throttle lever 4 for warming up the engine. A fast idle cam 9 has a control surface A that rotates as the engine progresses to guide the fast idle lever 5 in the closing direction, and a control surface B that engages and holds the fast idle lever 5 at a high opening when the engine is started. The rotation of the starting cam 11 and the fast idle cam 9 during warm-up biases the starting cam 11 in a direction to separate it from the fast idle lever 5, and the starting cam 11 resists this urging force. An internal combustion engine characterized by being provided with a relief spring 13 that can be engaged with the fast idle lever 5, and a back spring 4a that biases the fast idle lever 5 toward the fast idle cam 9 and the starting cam 11. Engine starting and warm-up device.
