Re: vro and how does it work?

What year is your engine?

You will most likely find the VRO pump attached to the breather box, the pump is black and has a bunch of fuel and oil hose going into it. You will want to ensure the pump is working but generally I don't think they don't go bad from sitting... unless it's an older pump without the newer alcohol resistant rubbers. Best bet is to run mixed gas (50:1) until you are sure the pump is moving oil. If it's a newer pump you can pinch the oil line (gently, use a rag and a pair of locking pliers) and it should alarm due to no oil flow, if your alarm system is working.
