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?

Thanks, Marv
