Haven't used my chain saw in many years McCulloch MAC 3818 18" 38cc. Just went to HD where am pretty sure I got it and didn't see them there anymore or any parts. Wanted to get the 2 cycle oil to mix up some gas and start it, but I guess I can use the generic and just mix at 40:1 as it says on the tank lid. I may have left it with gas in it (not drained) but it is empty now when I open it, so maybe I ran it dry. Any risk in trying to start it just adding new gas. Wouldn't think so, but just double checking. I know I had plenty of chain bar oil in there. That should still be there. Just wondering if there's anything needs done before starting it up after so long. It was never used much. But I would like to cut up some wood that's on my property.
