The pull string broke and i bought another one but dont know how to put in on

when it broke it may have unwound. the spring has to be wound up before it will recoil. you tube has many videos to show you how to rewind the spring. be careful as when wound up it has pressure on it. also be sure to back it off one turn past the string hole so if you pull all the way out it will not break the spring.

if its a newer mower take the top off the engine there will be a round plastic piece twist around till it stops stick a screw driver threw it to hold put the string threw your handles and back threw the cover you should see a hole in the plastic piece put in there and tie a knot hold the rope and pull out screw driver rope should wind itself up

Pull recoil and remove screw holding the string pulley. There's a spring behind it. Find where it hooks to the housing bend it to latch. This is what broke loose. Now wind it all into the designated spot. Attach string pulley and CAREFULLY put back together. Finally wind up insert rope and let it retract. This is a very difficult and frustrating job.

Search YouTube for videos on guitar stringing... very good source.

I saw this done by a guy, he was not working on a Buick ... he went to the bone yard to get a replacement window - I dont know how he got the old one out, probably cut the rubber on the outside ... what I did see was he put a heavy string into the rubber channel that was in the car and lubricated the rubber heavily with liquid soap. He set the bottom of the glass into the botton of the gasket. Next he started pulling the string out which spread the gasket wide and the glass just popped into place. I saw it, it looked simple, I don't know that I could do it. Maybe you should try it.

I guess the tipping point would be what is the cost to have it done VS the cost of your getting a used glass from the bone yard.

Good luck.

Thanks for visiting FixYa.com this morning ...

Replace the string that's why it broke.

To take the housing off, you may need to remove the carb choke houseing "becasue of a hard to reach bolt. A small oil filler tube screw and then a couple screws on the top. I dont know if you broke the rope or of the assemble inside is broke, but they make a kit for new springs and wings that is fairly simple to replace if thats the latter of the two.

I would discourage the average handy person from undoing the screw on the plastic reel inside under the cover and pulling up, as it is the metal band that creates the recoil tension and those are challenging still 15 years later. ;)

remove bolts from cover and remove the cover. Should be able to access the assembly for the pull rope. Go to a local mower repair shop buy some new line. The old line should just be knotted up on the spring loaded wheel in there. You put a new piece on put in a new knot, put some turns on the assembly to basically wing the spring so it snaps back when pulled, put line through whole and attach to pull handle.

Possibly binding somewhere when it is assembled?

in order to tighten your chain you can take a link off which would involve using a grinder, if you dont have one than go to an atv store and ask them to do it. theres a clip on the chain which holds it togther, remove the clip without damaging it than just pop the link off. that will take the chain off. i dont know what type off atv you have so there are probably bolts that hold pull the back end to tighten the chain look for those and if you can find them than tighten them.

for your engine do an oil change and drain out the carborator. if you need more help let me know.
