Why can't you pull the cord on your gas weed wacker?

Answer 1

Answer

Usually, there is only two reasons for this. The first is that the pull cord has simply gotten tangled and will need to be taken apart and re-threaded. I have a Craftsman model and it takes quite a bit to get the pull chord cover apart. My broke and I had to replace the chord. The second reason is usually that the piston as seized usually from lack off of lubrication and is usually not worth the time or the money to fix. Sometimes you cant even fix it cause the piston is almost welded to the cylinder wall when this happens. Hope this helps.

From another member 05-14-2012: There's a free solution to the seized piston. I have a Shindaiwa T230X grass trimmer. When I pulled the starter cord next time, it stopped dead at about 6-inches out. Wouldn't budge. My husband took a look. He said, "Isn't the fuel supposed to be greenish? Did you put oil in it?" Yikes! I had forgotten! Bad, bad! He then took off the starter assembly. He found nothing wrong with it, but found that the piston had seized. He took out the spark plug, cleaned that, then sprayed WD-40 into the spark plug port. He then poured 2-stroke engine oil right into the spark plug port. He also sprayed WD-40 around the little flywheel that the starter assembly snaps to. He gripped it with pliers, and got it to turn, but tightly. The compression was still good. Then he put back the spark plug, and the starter assembly, put 2-stroke oil in fuel and pulled the cord. The motor started right up, steady and strong and exhausted a plume of blue smoke. It runs as normal again. This is how it can be done.

Answer 2

Try removeing the spark plug, and see if you can pull the rope,

If not then it,s in the rewind remove it and check to see if the cord is jamed .

hi i know this might sound stupid but are you holding the safety/cutoff bar on other wise you don't get spark and it puts a brake on the engine
