Alarm buzzer and red light &am

Alarm buzzer and red light & Loss of power indicates shutdown of engine due to lack of oil from oil injection system. Check you tank on the engine as well as reserve tank for adequate oil. Bog down on acceleration could be clogged main jets on carb or other gunk. Thorough cleaning of carb or minimum high speed jets on lower side of carb.
