Stihl’s eat through line like crazy, even the gas models. I’ve had two gas Stihl trimmers since I left my parents house in ‘98, and the only reason I don’t have the first one is because I sold it to upgrade to the one I have now (I’m 6’1” and the curved shaft models aren’t as ergonomic for me as the straight shaft). The one I have now I set the choke and prime, pull twice, flip the choke off and it goes like a violated ape. Never had it be tough to start, same with my Stihl blower and chainsaw. That’s why I justify going through tons of trimmer line.
