Just picked up a new stihl br600 magnum and absolutely love this machine. I have read many post's on the do's and dont's using 100ll av gas in chainsaws. What about stihls 4-mix engines? The carb on this blower looks non adjustable. I have a small supply of av gas for my 60's vintage wisconsin engines collection that all winter until the summer engine shows. Any input?
