Echo make a good product but there is clear cost cutting in the last years. poorer castings, surface finish, plastics, etc
The aftersales parts are handled by briggs in australia - the way they do their parts listing for echo is absolutely pitiful.
The model bunnings sell has a white plastic throttle cable mount that is on the carby itself. It sits up like jackie way above the air filter housing and its pretty easily cracked off if you knock it or slightly snag it on your sleeve or a plant.
Sell it separately - no. That will be $140 for a carby thanks all for a $20 part.
Every time I start my 322l husqvarna I am happy I paid decent coin for a good trimmer. Echo was going to be my second choice.
