A good fuel mixture ratio for any 2 stroke weedeater or chainsaw is 50:1. That equals out to 2.6 oz of oil per gallon of gasoline. Most 2 stroke oils can be bought in pre-measured containers at hardware stores or small engine dealers. It is best to not mix more than 2.5 gallons at a time. Hope this helps, Daniel.
Your need to remove the starter recoil assy and check for damage. It will be obvious. Just remove the mounting screws and lift it off. It is not difficult. Use the first link page 3 to identify the parts you may need once you do the visual inspection with the recoil removed.
Empty the tank and then remove old lines, then get the new lines and place them over the, after that just get the tank full and prime up and hey presto it should start.I\'m presuming this uses plastic fuel lines.
