Troy Bilt trimmer starts and dies. Troy Bilt and Craftsman trimmers are made by the MTD Products company, so they have similar accessories.
However, if you’re going to replace your trimmer’s head with a different type of attachment, it won’t fix your problems.
Troy Bilt trimmer starts and dies
Troy-Bilt trimmers often start then stall. This can be caused by the carburetor being clogged with a mixture of fuel and oil that creates a slippery paste.
Try cleaning the carburetor first with carb cleaner if this is happening to you. If this doesn’t fix it, try rebuilding/ replacing the carburetor.
Faulty Fuel Cap
Fuel cannot flow in a vacuum. For your trimmer to run, the gasoline has to be able to move from where it starts in the tank.
To pull fuel out of the tank, something has to take its place, and that something is air.
Clogged Carburetor
The carburetor may be clogged. Clogging is most commonly caused by leaving fuel in the string trimmer for a long period of time.
Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance.
This sticky fuel can clog up the carburetor and cause the engine to stall. If this has happened to you before, try cleaning out your carburetor with carburetor cleaner.
Sometimes cleaning out your carb works fine and once spark plugs and so on have been cleared out its back to business as usual but if cleaning the carb isn’t effective then it might be necessary to replace or rebuild it depending on how much damage has occurred.
Fuel filter might be clogged
The fuel filter may be clogged. A common cause of this problem is that new string trimmer owners often ignore the fuel filter.
They might not realize that their string trimmer needs regular maintenance just like any other piece of machinery or vehicle.
Each time you use your string trimmer, the contents of the gas tank can mix with the air and form clumps of gunk in the fuel filter.
The result is a build-up called sludge that acts as an impassable barrier that prevents fuel from getting to your engine.
Rest assured it’s a simple fix! By changing out your old fuel filter for a brand new one, you’re sure to have your reliable string trimmer back up and running smoothly just in time for next season’s landscaping gig.
The spark arrestor is clogged
Over time, a spark arrestor can become clogged with soot and lose the ability to adequately stop any shooting flames from a malfunctioning engine.
If you don’t have a functional spark arrestor, your motor may stall unexpectedly.
To cleanse a spark arrestor, remove it from where it’s located (usually under an air filter) and clean it with a wire brush.
If this doesn’t work or if you want to be proactive about preventing future buildups of carbon, consider replacing the old model with some new inexpensive ones that are readily available and easy to install yourself!
Bad Fuel
Fuel that is not the right kind has too much ash, or other contaminants can cause your trimmer to stop working.
The best thing to do is to take it back to where you got it and fix the issue for you in order for you to continue having a happy ride!
Dirty Air Filter
When the air doesn’t flow through your trimmer engine, it’s a lot like when the fuel doesn’t flow.
You may get the machine started with some air already in there, but it will stall out almost immediately unless you can find a fix for this problem.
You should change the filter roughly once every three or four months (or after about 20-30 hours of regular use) when you’re using your trimmer regularly.
Cloggy Exhaust
Exhaust isn’t something to forget about. It can be easily overlooked just as the fuel and air require a clear flow for input on the one hand, but there must also be an outlet for exit on the other hand.
