  1. I was told the four stroke motor (because it takes no oil in the gas) the ethanol in the gas eats the rubbers in the carburetor as well as the gas lines that you have changed from the looks..

  2. I have the same problem (won't run above idle) but I don't remember having taken off any gasket, it's practically brand new. I wish the gasket had been better pictured in the video, I have no idea which gasket gets referred to. But thanks for the upload, maybe it'll get me going in the right direction. Also, I fucking approve of the language used. lol

  3. I HAVE A TB575SS WILL NOT STAY RUNNING JUST LIKE THIS ONE EXCEPT THE GASKETS ARE NEW AND STILL LEAK AIR SO I AM GOING TO BUY A NEW CARB THEY ARE ONLY 45$ BUT I HAVE A HORRIBLE ISSUE WITH METAL IN THE OIL ANYONE ELSE HAVE THAT ISSUE

  4. Hello, we have one of these TB685EC 4 cycle trimmers, about a year and a half old, not many hours on it at all. Recently it has had issues with running and also leaking oil. I believe that I have solved the oil leak issues by tightening the bolts that hold the bottom of the oil pan and oil filler/sight glass on.

    I also cleaned the carb. What I noticed is that when it is cold it will bog down if you give it any throttle. It seems like pumping the primer will give it more life, as if fuel delivery is a problem. However once you get it running hot you can max the throttle and it won't have any issues. I'm not sure what the problem may be, I was thinking that perhaps the carb might need a new diaphragm to control fuel flow. What do you think? The carb is clean otherwise.

  5. The weed eater I have will start, but idle roughly. I'm not sure where to start at and it'll run idlin, but then if I give it gas and try to cut somethin, it stalls. I believe it has somethin to do with the carb on it but not sure.

  6. I screwed my spark plug in Crooked on my Troy bilt weedeater # tb575 EC. I think I need a new engine now, where can I get one or do I need a whole upper shaft and where can I get it

  7. You need to steady your hand when your recording. Shaking you camera the entire time is frustrating especially during a video you trying to learn from troubleshooting issues. Overall – thanks! 🙂

  8. Thanks for the video. I replaced the primer bulb and I think I also put the gasket for the carb on wrong and I am having the bogging down with throttle issue. And I agree my carb has pissed me off too!!!

  9. I just bought one of these and it says unleaded fuel only. Do you know if super unleaded would be alright? Your video will be helpful if I ever have a similar problem.
