  1. Hi can you show how to install #490179 do I actually need that part holding the spring when new can the old one be re used

  2. The spring retainer needs to be on the spring to hold it tight. You can take it off when you set it in place in the starter housing. If it comes apart before you get it in the housing it is real hard if not impossible to rewind. The holder on the spring is not sold separately. We do not have a video for this part yet.

  3. Because of your video I attempted & successfully changed my pull cord with some 3/16" rope I got at Home Depot.  Thanks!

  4. Very well put together Video.  My biggest concern was how to set the spring properly with the tension.  Thank you for this!

  5. Great step by step instructions! Easy to follow and saved me $$$$ and time. I think I will treat myself to an expensive craft beer and lunch after I watch my son mow the lawn! LOL. THANKS!

  6. I am in process of replacing my pulley at the moment and when attempting to put new one in and turn counterclockwise 5 times…there is no tension. What am I NOT doing correctly?

  7. Thanks to this great video I replaced this piece recently after being told by the manufacture that this was my issue  BUT
    it did NOT solve my problem regretfully

    My mower has an 'easy start' when you pull it a couple times you pull the lever and then it starts for you( No battery). Well when I pull it to 'wind it up' it doesn't have enough 'spin' to kick the motor over.. this piece seems to only control the rope retracting properly. am I wrong about this assumption?

    Would you be able to direct me to which part may be the issue on my mower. Thanks so much

  8. I took the housing to the store and asked for a spring, providing all the details of the engine and chassis, £35 to supply and fit, £15 to supply.
    I went to Almend in Hitchen and the guy supplied me a new spring for £7.85 
    I watched your video and fitted the spring myself. 
    The tensioning the spring was the key to my success. Thank You For Posting

  9. This has the perfect amount of information and detail….not too much and not too little. It made this a 15 min job…..thanks very much!

  10. I agree with Gary, This had the exact amount of information needed to get the job done. Instead of having to take my mower to a repair shop, I only spent $6 on replacement part and fix it myself in 20 minutes.

  11. Thank you. I had to watch another video on how to get the spring back inside the pulley when I screwed up the first time. I especially like how you showed to wind back the pulley approximately five times.
