I have a redmax trimmer and edger there both the same engines and both have the same problems... The trimmer model number is BCZ2600S i dont know the edger off the top of my head but im pretty positive there the same engine size and its a straight shaft.... but anyway ever since day one when these machines are started up and after giving it any gas they both just die and shut off. Also after sitting all winter i went to start up the edger this year and it starts just fine but i let it sit for over a half hour just letting it run and warm up and went to pull the throttle and what do you know it dies. the edger is still brand new i have only put one tank of gas in it so i have no idea why its giving me such problems but im not real satisfied with the redmax trimmer and edgers so far. If anyone else has had these problems and or has any ideas to cure this problem i would greatly appreciate it!
