Hey guys, im pretty rook when it comes to maintenance, hell even that may be an understatement. I haven't been running any maintenance on the trimmers or blowers and ive noticed that they begun to lose a little power ( the back packs atleast). Nothing major, just not what they used to be. I run echo 770 and redmax 8500z (almost want an excuse to get rid of the echo and get another redmax, power is way better at peak performance). They are both noticeably a little less blow power, any insight on how to get them back to prime condition? It could also be the shitty gas/oil 2 cycle mix ive been using so im not sure. The trimmers i use are 225 straight pole trimmer and a 265 power head with trimmer/hedger/edger attachment. The trimmer is in real bad shape, needs oil/gunk clean off it but it still runs real well. It's time to learn to take crap apart and keep my stuff running nice, just not sure exactly what im doing and would like to know from the best, Thanks guys!
