    couple different ways, does the pulley the rope winds on have a small slot in it, if so take some slack on the starter rope and put it in there so you have enough to hold the rope and turn the pulley in the direction to put more tension on the rope it might take a little time but that is the safest and easiest way to do that. Let me know if that doesn't work and I will look at a schematic and come up with something else.

Yes, it is possible that the spring needs to be pre-tensioned. its also possible that something was put together a little out of alignment, or some part is too tight and its too hard for the spring to wind in the chord. try to reassemble the chainsaw with a couple more turns on the spring and see if that helps.

SOURCE: Chainsaw pull cord won't pull to start

Simply check to see if motor is locked is to remove spark plug and try to pull start. If motor turns, then he may have gotten gas in cylinder and created hydraulic lock. If moto does not turn, it is just a few screws more to take side cover off and see if rope caught in pully. In fact, you may want to take side cover off first, and make sure rope pulls out of housing, and self winds, like it should. At hat point, he can simple turn flywheel by hand to see if motor is locked up.

If the motor is locked up, you can put small amount of motor oil, (half a tea spoon) into spark plug hole, let it sit half an hour or so, and then try to work the flywheel back and forth to break it free. This condition may have been caused by running straight gas, not mixed. And, even if motor frees up, it may still need to go in for repair.

We have a couple of Poulin Pros at this saw mill where I work, and have had the piston lock up more than once, from guys dumping in straight gas. Sometimes we'ra able to free up piston, and make saw run again. And sometimes we end up tearing it down and repairing piston ring. Good Luck

SOURCE: my chainsaw cord would not retract when i pulled

Your spring is probably broken. You just need enough tools to take off the cover. One end of the spring fits over a peg or mount in the casing and the other end on the sprocket. One end or the other is probably broken. Both ends need to be attacked and then you set the sprocket or pulley back into the casing. Before you do, you spool most of your rope back onto the sprocket or pulley. Somewhere on the pulley you will see and indentation so that you can set it back into the case but the rope remains on the top of the pulley. You keep the rope outside so that you can then wind up and tention the spring. The number of turns you need to wind up the pulley depends on how much rope you have that isn't on the pulley. It should take about 4 or 5 turns of the pulley then you stop the indentation on the pulley where the rope enters the case then pull on the rope handle as you feed the rope out the indentation. ONce all the rope is back outside the case or on the pulley, you can let the pulley go and the spring should have enough tention to wind it all up again.

SOURCE: Chainsaw pull cord wont tension up

Its almost certainly made by Poulan.
This may help you find an IPL at Sears, they are available:
http://www.searspartsdirect.com/partsdirect/modelHelp.pd?modelNumberId=29
This lists all Poulans. It will be difficult to find your saw but it is here:
Poulan.com
http://www.ordertree.com/modelinfo/POULAN-WEED-EATER/75.59.html
It sounds as though the starter spring is broken.
This thread explains how to reinstall the spring.

The IPL for your saw shows all the parts and provides an idea of how they fit together. GL

Can not pull cord all the out to start the saw


Sounds like the pull cord has become trapped round the spool. Remove starter housing and unwind the pull cord manually off the spool. Then wind the cord back on by hand. Be careful because the spool will be under tension from the rewind spring.

The pull rope will not rewind. How do I reset it?


The cord should be removed from the spool entirely, then wind the spool spring CCW for a number of turns making sure the spool can be turned for about 6 turns more (during start). Wedge the spool so that it can't unwind the spring again. If the old cord was about worn out, replace it with fresh. Melt the cord end somewhat so that the knot won't pull out, then tie an overhand knot in the cord end. Feed it into the inner retainer on the spool, then thread the cord around the spool 5 or 6 times in a CCW direction. Once wound, feed the loose end out of the cord port, slide the pull handle on, melt the cord end, and tie an overhand knot on it. Stuff the knot into the handle and release the wedge from the spool so that spring tension pulls the cord tight. Pull the cord out several times to make sure nothing interferes with cord and mechanism, then install on the saw and check the start operation. The spring should never bind-up when the cord is fully extended. Hope this helps!

The pull cord will not retract back into the saw. When I tried to start the saw, I pulled the cord and now it did not retract back. It is all the way out and will not recoil.


When I have had this happen it means that you need to manually rewind the cord and put some additional tension on the take up pulley. To do this you'll have to open the saw up and untie the handle. Turn the pulley like one turn, put the rope back through the hole and tie the handle back on. All this is done while maintaining tension on the rope.

Stihl Farmboss - cord will not move


try taking plug out to see if it turns then.if not take off pull cord assembley to see if something has come loose and jammed flywheel, failing that could possibly have snapped the piston ring and jammed. oh yes one last thing check clutch if you have chain brake on and clutch is jammed obviously wont turn.

How do i get the pull cord spring back in on a


Recoil Spring Rewind
I invert and secure the housing and rewind the spring large coil to small (need eye protection, both hands and no women around work area!). I'm right handed so I tension the spring enough to insert it inside the previous coil while holding what has already been installed with my left about 180° from my right hand. The tension will hold the spring in the housing once completely inserted. Then bend slightly the inner most part to engage the starter spool. It will require about 2 turns of pretension for it to retract properly. HTH

The pull cord has come off the spindle, how do I get it back on properly or install a new one and reset the spring tension


Remove the starter cover, rewind or wind a new cord onto the spool. Turn the spool about 2 turns against the spring, thread the pull cord through the starter cover and reinstall the pull handle.

Lawnmower Starting Pull Cord Replaement


There will be a piece of casing that holds the starter mechanism in. Usually held by 4 screws (probably torx screws unless it's an old machine).
Undo these screws and you will find the cord carrier inside.
Observe how the starter dogs are located, and how it all goes together.
You may be able to remove & replace the cord without taking the carrier off the casing, but it is probably easier if you do.

Then you simply remove the old cord, thread a new cord through the hole & tie it. Reassemble the carrier onto the casing. Thread the cord out of the casing & through the handle, tie that end.
Then wind the cord around the cord carrier until there is a slight tension on the spring.
Screw the casing back on the mower and you're away.
