I have a Troy Bilt TB685 30cc weed trimmer which starts up ok but when I press on the trigger for more power its stalling out. Could it be the Carb or the Fuel Lines?

Hello. Let me assist you. Since your trimmer runs but stalls at ful throttle it is telling you that there is a fuel problem. Not enough gas is getting through the carbeurator to satisfy the engines needs on full throttle. Most likely the carbeurator is gummed up. A common problem. Let's see if we can un gum it by getting a can or carbeurtor cleaner. Go to any auto parts store and talk to the clerk about your need.

Sounds like you need to take the carb. apart and clean it. I like to use a Den Tek Brush, (used for cleaning teeth), to clean the small ports in carb. they work great for this job. Make sure to either clean or replace the small screen in thcarb. as well.

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please do not forget to rate me,
Thanks,Good Luck, I hope this helped
