I have a Homelite 180 # UT-10721-B. the automatic oilier is not working. On this particular model the oilier is pressurized from the carburetor. I have checked all the connections, lines, rebuilt the carburetor, and found the duckbill valve and screen pickup working. I think the carburetor is not pressurizing the oil reservoir. As I said I replaced the diaphragm in the carburetor so that is fine.
Hate to give up this saw as it works wonderfully otherwise.
Any suggestions to get the oilier working again?
