I've had an Echo for 10 years, run it hard, do a lot of trimming, use about a gallon of premix each month. How long should this Echo last? I change the a/f, f/f and plug frequently and grease the trimmer head, but do nothing else, not even adjust the carb. I use Red Line and mix it at 50:1. It starts on the first or second pull and runs great. Is there any more maintenance to do? Do you just run it until it won't go anymore and then fix/tune it?
