Change all fuel lines in a McCollough Chain Saw, new fuel filter. How far does line from the primer go into the fuel tank. Just on edge, barley or in a few inches? I get it started but it goes off after about 30 secs running, almost like fuel isnt getting into the engine?

It should be as illustrated on the link.

The line with the filter needs to be long enough to reach all parts of the tank as the saw is moved. The return line is not a critical length probably mid tank. Do you have the filtered hose feeding the primer and not the carburetor? That will cause what you describe. HTH

McCulloch Manuals
Illustrated Parts Lists: (IPLs) are fairly simple, on the underside of McCulloch saws is a black and yellow tag; the upper number (“Power Mac 320” 600021H) is the model, below it a serial number (11-18555). These 2 numbers are combined to create an IPL number (“Power Mac 320” IPL number = 11-600021H). The IPL number can be used to find the correct IPL for every McCulloch parts supplier I have found. If the parts supplier only list part numbers the proper IPL is the source for the part number.
