So i have and have had mostly echo and honda trimmers and have used other brands also. So today i used my buddys fs130r (4mix) and his fs250r (2 stroke) and i like both machines except for 1 thing. The throttles are snapper which is nice but way too much like a light switch especially the 130r. So if your mowing like a maniac in high field grass it doesnt matter because the throttle is pinned. But, if you are trimming grass that grows weekly it is like impossible no matter how smooth you try to be it is hard to keep constant rpm smoothly. Why are stihl trimmers like this. Is it because neither has any freeplay when you pull the throttle? very light flywheels or what. I tried his redmax trimmer also and it had a 2 stroke that was not as powerful as 250r but super smooth motor. The fs250r actually vibrates more then i thought but it felt just a hair lighter then the fs130 even though they say the weight is both 13.2 i believe. Anybodys thought would be appreciated. BTW I have never used a trimmer with balls up the @$$ like the fs250r, what a beast.
