Oil alarm

[spareparts]

most likely the oil gear. You can check for voltage coming from oil pump sensor while the engine is running. If you aren't making any voltage, pull the oil pump, coupler and gear, shine a light in there and see if you see the gear. I've seen a bad sensor, a stripped coupler, and most of the time, stripped gear. Mix up a small tank of premix to run teh engine off of while testing
