I completely understand your need for the oil/fuel ratio to your chainsaw. While you are waiting for your expert answer, I did some research on the unit. At this time, I was unable to locate information that would be helpful in regards to your question. Some of these questions that are asked will need specific research and will be answered by an expert with-in two business days but usually sooner.
The screws on the carburetor should be screwed in all the way until they stop. Then back each screw out 1.5 turns. From there, you'll need to adjust each screw in or out 1/4 turn at a time until the engine runs and accelerates smoothly.
The ration of oil/gas for that saw should be 16:1. So you'll need to add 8 ounces of 2cycle oil for every gallon of gas.
