I've learned a lot in the last couple years thanks to all of you and one of the next things I need to educate myself on is cleaning and replacing lines and filters on a McCulloch trimmer.
The symptom and reason that I am doing this is that it will only run on half choke. Open the choke all the way and it dies almost instantly. That would tell me that I have issues in the fuel system, I suppose.
is there any particular thing or part or whatever that I need to pay particular attention to?
