Sounds like you will need to clean your carburetor. Sounds like you have gotten some trash in the cauburetor, check your fuel container to see if more trash is in it.
Sometimes you can get by with priming the carburetor 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/weedeater 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, You will first seat the jet screws and 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.

Troy-built tb80ec will only run in half choke position


Reality. Place unit in trash. Every post about this model has same gripe. After short usage it: 1) only runs on half choke. 2) won't start after getting hot 3) has inaccessible fuel adjustment other than idle.

The unit is crap.

If you rebuilt the carb did you turn any of the screws on the carb while cleaning or take out, you might have just the low idle screw closed a little to much open half turn and see what happens. If you look at the carb where needle screws are located on the side,if you have two screws it will be stamped with an " L " and?or an " H " next to each screw. If you only have one screw then turn that one, to left to get more fuel. Good Luck...

My troy built starts but will not speed up enough to use even after it warms up. It is 2 years old but only has 3-4 hours of use on it . Can you help me?


Is it 2 cycle or 4 cycle? Meaning, does it take plain gas, or mixed gas?

Clean the plug, clean the carb with either choke cleaner (4 cycle) or wd-40 (2 cycle) by spraying it into the choke hole after you take off the air filter.

You may also want to spray some of the choke cleaner or wd-40 into the gas tank with the gas to help clean out the whole fuel system.

Only use choke cleaner for 4-cycle regular gas units. For mixed gas, use wd-40 in place of choke cleaner.

Try to start it and then go back and forth from half choke to full choke until it starts picking up.

Hard start tb475ss troy built weed wacker when i close the cold start lever it starts but its 75 degrees out its like the primer ball is inop but i see fuel moving through the lines when priming did not...


These 4 cycle trimmers need to be primed 10x before a cold start. The bulb will feel *firmer* on the last two or three depressions and you'll know that the carb is primed.

Full choke and and full throttle on first tug should see it hit once with a puff of smoke. Second start attempt should be in choke position two (half choke) and with full pressure on the throttle. Should rev to life on start attempt. Let the engine IDLE for 30 seconds, moving the choke to off at the end of the waiting period. Let engine idle to warm another full minute with no choke, then set to work!

Troy built weed eater won't feed line


Check the size of the line,(OD), make sure you are using the correct size, sometimes cheap line will be problematic, also, you said you are re-stringing it, try a new batch of string, the old string inside the hub can get chaffed and will stick to itself...

Fuel line size for troy built TB20CS weed eater


You probably have found the solution by now I would assume... TB won't tell you this because they want you to buy their stuff..
You probably are looking at the 0.08" diameter that's just a bit smaller than the 3/32". Hope this helps....
