The fs 90 is a four stroke engine, but by some jiggery pokery it is designed without a sump, you must use 2 stroke fuel, 50 to 1 if you are using Stihl oil, if you use it without 2 stroke oil it will die in short order.
Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
