What I do with my stihl saws is after starting I let it warm up for a few seconds and then run it at full throttle for about thirty seconds. If your saw does not want to keep running I would check to make sure air filter is clean. Next you can adjust carb.setting for idle and hi speed,check your manual for instructions. Also I would remove and clean spark plug,check gap and reset or replace as needed. Make sure your gas oil mix is proper and gas has not been setting for a long time,no more than a couple of months without some type of fuel stabilizer. I use either STA-BIL or sea foam at a rate of 2 to4 ounces per gallon of gas. About the only other thing I might suggest is to check the feul filter. They usually are located on fuel pick up line inside gas tank and can be a pain to get to. Good luck and I hope this helps Thanks
