Troy bilt weed eater

Change the line on Troy Bilt 4cycle TB525EC weed eater

sounds like your flex cable has taken a trip south. Pull the shaft off the head and take a look at the flex cable. If flex cable is ok, they your clutch is defective.

Your air filter may be plugged, your pug may be fouled, or your carb may be gummed up.

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...

Replacement head can be purchased from amazon, here Amazon com troy built head. I hope this helped you. Have a nice day. Vince

troy built is pure trash ill never waste money on any of thier trash agin i have a weed eater 5 months old it wont even crank pure china trash

I just had this same issue. I found out that you have to take the cord out of the handle then put the spool in. You then rotate the spool back in and align the spool with the spring and fish out the cord which will put a small amout of tension on it. You keep the tension on it and put the handle back on.

I had a similar problem with my troy-bilt weedeater. I tried replacing the sparkplug, replaced the fuel filter and etc. It still would not start. I looked at the troubleshooting guide in the owner's manual and it listed a possible cause as a clogged spark arrestor. I cleaned out the spark arrestor by taking it off and cleaning it with a wire brush. Now it runs like brand new again. I hope this helps.
