Instead of using a petrol oil mix have you ever thought about using one of the pre-mixed alkylitic fuels ? Husqvarna do their own another is called Aspen2 . they contain NO ethanol to rot out fuel lines or any other rubber bits or any of the other harmful chemicals that get added to fuel,and its evironmentally friendly . I've even found in small two stroke engines it'll de-gunk a carb the other added bonus is ..... it has a higher octane rating too
