A two-cycle engine having an oil pump (19) driven by the engine crankshaft (11) to supply lubricant to the carburetor (12) has an alarm system to warn of an interruption of the oil pump drive. The alarm system has a signal processor (23) connected to activate an alarm (27) should signals from an oil pump rotation sensor (26) be interrupted, if a level switch (28) in the oil tank (20) indicates a low oil level, or should a signal from the ignition system (14) be interrupted. The signal processor (23) is also connected to briefly activate the alarm (27) when the engine is started to provide a test of the alarm system.
