Sounds like you will need to clean your carburetor.
Be sure to use compressed air to blow out all the fuel and air passages.
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.

SOURCE: I have a 2 cycle Troy-Bilt TB90BC line trimmer.

One of three things is occuring here. The IDLE SPEED SCREW (Phillips head) on the throttle plate is screwed in way too far. The L and H mixture screws are open way too much allowing the carb to use excessive fuel, even on startup. Those 2 screws may need adjusting. The metering lever in your carb is not adjusted flush with the carb body flange and is holding the gas needle open constantly. Check these things and post back.

SOURCE: Troy Bilt model TB90BC trimmer won't stay started

new formula gas is HORRIBLE for carbs on small engines, especially if they sit over a winter. the ethenol (actually White Lightning) is almost pure alcohol so it absorbs water before evaporating and leaving corrosion and water in carb. DO NOT use gas that has sat for any length of time. i never mix more than a gallon at a time. the openings in these small carbs are less than the diameter of a straight pin so just about anything will clog them up. NEVER run without an air filter and keep it clean. it is not difficult to install a new kit but just make sure you remember the sequence when you reassemble the carb. some kits have more parts than you need as they fit other models so match your old parts with the new ones b/4 reassembly. helps to be a watchmaker instead of a mechanic when you r and r a carb. most problems are old gas, varnish, stiff parts, clogged lines or openings, air cleaners, etc. hopes this helps.

My troy bilt snow blower that i bought last season (new) ran great i drained the gas at end of winter and this year is hard to start and runs poorly stalls often and bogs down spits and sputters and also...


I am guessing you did not run a gas stabilizer through the unit. Start the unit and run it while spraying carburetor cleaner in spurts into the carburetor. What has happened is that the small amount of gas has dried or what we call varnished causing internal parts to stick. If that fails, removed carb and disassemble and clean, reinstall.

I have a Troy Bilt TB90BC. It starts fine but doesn't want to run unless the choke is on or the engine is revved all the way. Any thoughts?

Troy-Bilt weed eater, Model TB90BC, had rotten fuel lines and primer bulb, I replaced but may have hooked them up wrong. How do I hook them up?


Prime and watch the fuel move up to the carb. This is the fuel line and it should be long. Make sure it goes to the bottom of the fuel tank.
