Stihl blower spring problem

[Jlgriff97]

Can anyone suggest why the spring inside my blowers pull cord assembly keeps bending. It’s not the recoil spring but another I believe it’s the ergo start spring? I replace it and when I pull it jams and the spring bends. Any help will be great thanks

You will get through a dozen of those one after the other once that's happened, and that recoil unit will never be reliable again. It's an inherent fault...so much so that as from this year Stihl had dropped that soft start system on their blowers.

 

They started playing up about 3 years ago...don't know why, but we fitted new springs and shortly after they failed again. We no longer repair the recoil units, we simply buy a complete assembly and bolt it on....cost a bit more to start with but cheaper in the long run OR you could just replace it with the non soft start version.

 

Don't bother fitting a new spring it WILL go again very shortly

Im on my third spring 😬 it pulls fine as long as the spark plug isn’t in, perhaps that will help somebody come up with a fix

Don't tend to start very well like that though.

Richard1234's comment- done the same as what we do

Perfect thank you

Replace the item with the unsprung equivalent part off the earlier model and it's sorted, I can't remember the part number but I fixed mine a few years ago, it's a straight swop out and the problem's sorted👍

its all to do with too much fuel in the cylinder creating greater compression from missing the pop when when first starting if i recall correctly from a post a few years ago. The solution was to get the standard rope rotor about the price of the ergo spring and fit that.

I read that and my response stands, get rid of the pulley rotor and replace with the single solid pulley rotor without a spring. I think the issue is caused by a bit of wear but is bloody frustrating.
