ABSTRACT:
An adjustment prevention mechanism comprises a stationary covering member disposed opposite to a head of an adjusting screw for adjusting fuel flowing in a slow speed fuel passage in idling of an engine, and a cap-shaped plug. The stationary covering member is secured to something within an engine room, for example a suction pipe of the engine, and has a hole through which the adjusting screw is adjusted. The cap-shaped plug is inserted rigidly in the hole to blockage the hole after the adjusting screw was adjusted, so that the adjusting screw can not be readjusted by usual users after the engine is transferred to the users.
