First thanks for letting me join. I have a Lombard Super Lightning saw that doubles as a bug fogger. I understand the chain oiler leaks oil into the cylinder. Would someone be kind enough to explain how to repair the problem? (duckbill valve?) I understand that is the problem. Would someone maybe have a link to the repair manual for this saw? Is the oil going to hurt if I run it like it is? Seams to run fine and I really don't use the saw much. That being said I don't like something that isn't right.
