Does anyone know what the part number for the plastic piece that slips into the bar oil port hole? Appears in a crankcase diagram I found, but wasn't listed.

Also, is my saw pissing bar oil because that piece is missing? I've closed the adjustment screw on the bottom and just barely cracked it open, and thoroughly cleaned under the oiler plate and used a paper clip to poke that one valve thing. So this missing piece is all I can think of now.
