I have a MS260 pro chainsaw. When the saw is about 1/2 a tank or less of fuel it will not stay running. I know the obvious answer, never let the tank get under 1/2 full but I would like to figure out what the problem with the saw is. When the saw is under 1/2 a tank it just dies out. It does seem to try to restart but it just sputters. The first thing I checked is the tank vent, that is fine, opening the fuel cap to let more air in doesn't help. I thought it could be sucking air, so I put on a brand new Stihl fuel filter and fuel line, same problem. I rebuilt the carb just for the heck of it, cleaned it all out, made sure the gasket between the carb and the cylinder was good (so it wouldn't be sucking air there). I am obviously overlooking something but what? When the saw is full of gas or near full the saw runs great, starts fine but under 1/2 a tank is when I have a problem.
