The type of gas you use to fill the fuel tank is one thing you don’t want to get wrong. Getting the fuel selection right and caring for it properly will reduce the problems that develop from running old gas. The type of fuel and how quickly it is consumed are important to obtain good performance from your trimmer. The lack of fuel due to the varnish and deposits causing restrictions in the fuel system will result in a sluggish string trimmer. When the ethanol and water mixture evaporates, it leaves behind gummy deposits and varnish. Most gasoline includes ethanol, a plant-based fuel, that naturally attracts moisture to the fuel system. Old fuel can begin to break down and become less effective as soon as 30 days after purchase. The first thing I suspect when an ECHO string trimmer begins to run rough and bog down is the fuel quality. 8 Reasons Your ECHO String Trimmer Runs Rough & Bogs Down Old or Bad Fuel Causes an ECHO String Trimmer to Run Rough
