Hey guys, Wanted to thank everyone who helped me with my oiler problem on my371. It was that small plastic gear,I think it was $8. The next question I have is about chains,For as long as I had my saw I have been running stihl ripping chains and love them,Well when was cleaning up my saw to fix the oiler I realized that my bar is 3/8 by .058 and I have always been running a 3/8 .050. Is this somthing to be concerned about, and if so could my bar be ruined. I would really like to keep running this style chain what are my options? Get a .050 bar,or does stihl make a .058 ripping chain, or should I start over with a new bar and chain. Does anyone know what bars would fit on my 371? Sorry for all the questions. Chub
