SOURCE: put string on tb425cs troy bilt trimmer

there are two ways to install the string..the cool way is without pulling the inner reel off the trimmer..just leave it in place..cut (2) approx.two arms length (thats spreading your arms out like airplane wings) of .095, align the arrow of the inner reel (it turns counter clock-wise..the arrow points outward) with the arrow on the outer spool (pointing inward)..holding the spool and reel together so the inner reel doesnt move, push one of the cut strings through the eyehole in the side of the outer spool, and it should come up to the right, through a slot next to a small round hole the diameter of the string..if it doesnt, it just missed the exit (as i call it)..pull out and try again..let about an inch come take that end of the string and push the line into the little round hole until it stops, which should be about a little more than 1/8 of an inch..hold it in while pulling the excess line outside the spool to keep it in do the same with the other string for the other side..once you have both lines in place, turn the inner reel counter clock-wise to draw in both lines through the eyeholes of the outer may or may not get all of the line to wind in..not a will still have enough to do what you need to do..just cut off the problem you may or may not have that i do most of the tyme is that it gets hard to turn the inner solution is to bump the top of the 'bump knob' with your fist, then pull both strings at the same tyme, then continue to turn..this method is quicker and easier than the second way of having the inner reel out and trying to wind both lines at the same tyme and trying to place the reel back in the spool..hope this works for you...

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.

How to replace troy built tb25cs primer bulb?

The primer bulb has two clips that fit into a slot. You will have to squeeze both clips to pull it out. Make sure you remember which fuel hose went on each nozzle of the primer. There are two nozzles. Make sure you put the fuel line back on the same way. The part # for the bulb if you need it is a Walbro 188-512-1.

Which fuel line is the intake line at the carburetor?

The fuel line goes:
  1. From the filter in the tank to the carb, usually the bottom most connector.
  2. From the carb to the Primer. The tube in the center of the primer bulb.
  3. From the primer, outer tube to the fuel tank.

Primer bulb does not work

if you have gas in the primer bulb its working. gas is sucked from tank to carb , out return tube to primer bulb and back to the tank from the primer bulb. most likely dirt in carb or hard diaphram not opening needle valve allowing fuel to be sent. carb kits are around 12 bucks . but carbs for troybilts are usually only 20 bucks. I would just replace the whole carb if the case. if the bulb stayed empty I would look for broken fuel line in the tank that holds the fuel filter. they rot and break off within a year or two.

Troy-Bilt TB425CS Grass Trimmer. The purge/primer bulb does not pull fuel from the fuel tank.... There is no visible fuel in primer bulb when the bulb is pushed.

You may have a fuel line, fuel filter problem. I recommend inspecting and/or replacing old fuel lines as they get old, brittle, flaky, and develop pin hole leaks in the fuel tank and around the carburetor fittings. If you choose not to replace them, problems will surface down the road. Sometimes the check valves in the carburetor that open and close to keep the fuel moving in the proper direction malfunction. They can sometimes be cleared with a lubricant such as WD-40 but real strong solvent tends to ruin them. A primer bulb on the carburetor is easier to service as you can remove the primer bulb base assembly (mounts on carburetor with screws) and spray WD 40 liberally into the pump area. A remote bulb is a little trickier, as you have to either inject the lubricant spray into the fuel lines and attempt to get the bulb to draw it to the carb to free check valves inside. This is if you don't want to remove the lines and service the carburetor. Also, a new bulb may be needed. Thet deteriorate the way the fuel lines do. They are rather inexpensive and you can get kits that include the new fuel lines, filter and bulb all together. Some of these parts are available in the garden center at Home Depot and many are on Ebay. Post back if further instructions are needed.

Are there two tubes connected to the back of the primer bulb?
If it is connected, then the primer bulb itself could be cracked, allowing air to enter, but not fuel.
See if you can gently pry or possibly unscrew the bulb for replacement. They are readily available.

Can't help with the tank, but your better auto parts stores do sell an epoxy that is designed to seal plastic fuel cells.
