It is difficult to diagnose a no start problem without the machine being on hand. You need to check for blue spark, fresh oil and fuel and a clean air filter. You also need to verify that the engine isn't worn out and that it has compression. To try and get it to start, remove the air filter and squirt some aerosol type carburetor/choke cleaner into the opening to the carburetor. If it runs a few seconds, that is good and eliminates some of the causes. It may just need a good carburetor cleaning. Post back with results.

I have a Troy Bilt 4 cycle trimmer, TB475SS. The small fuel line in the gas tank has come off. I is about 6" long with a filter at the end. The trimmer can not **** any gas. How can I reattach it...

i would suggest to change all you fuel lines. troybilt uses specific fuel lines that they sell. you cant use your regular tygon fuel lines.

Pull starter

easiest thing is to take it off machine-that is the housing holding the string/handle-usually 4 screws-very easy(they may be allen wrench screws)and take it to a local lawn place and ask them if they rebuild them or if its cheaper to maybe just buy/order the entire thing if they have it/can order.It would probably cost 20.00 tops for the new housing with string and handle ready to go.Hope this helps

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!

Troybilt 4 cycle trimmer (TB475ss) won't start. New tank, new plug, new gas??? Will occasionally start, run for about 10-15 secs, then stops. Won't restart. Help!

Take the plastic cover off that covers the muffler and cylinder head. I've had 2 cylinder heads crack. The trimmer still ran but had little to no power and would not throttle up. First head cracked at the head bolts. The second one cracked above the bolts. The side that has the carb and fuel tank is harder to see and you must remove the carb and fuel tank to check. Also I've read online that this trimmer has a problem with the fuel line cracking at the bulb and in the tank.

My TB475SS starts and then dies right away. i

It usually wont idle very well when it's cold, Goto #1 on the choke give the rope a couple of "quick" tugs, and then move it to #2 Give it one or 2 more tugs with a little throttle, now it should be running witha little throttle, let it run like that for a minute then move it to #3 kinda still pumping the throttle a little and it should take off fine. If this is the 4 stroke, mine did the same thing until it was broke in good. (About 4-5 uses), now I have to say its more reliable than any 2-stroke I've owned and I use it commercially. 1st or 2nd pull everytime and is ready as soon as it fires! Hope this helps!
