[Husqvarna 445 Pull Starter Problems]

Basically either the string won't retract, or the starter won't engage with the engine (sorry I don't know the names of all the parts).  

 

Sometimes, if I get everything tightened just right, it works.  For a few starts, then it goes back to its usual tricks.  

 

I've seen the string catch like in this video @1:06.

 

@1:36 he shows where his part is warped and ovalled, but mine looks o.k.

 

The other side looks good too.

 

The Husqvarana kit to replace this is nearly $50 on eBay, which is a heckuva lot considering the original parts didn't go 2 years without trouble.  

 

 

 

 

[New Dewalt DCF899P1 Impact Wrench]

Tried to use it to break free a bolt that is only torqued down to 250 ft/lbs.  The DeWalt couldn't didn't budge it.  The battery is fully charged, I set the wrench on "3."  I can't figure out why it didn't work.  I got a smaller bolt out - as far as I can tell the tool is in good working order.  It doesn't appear to be a counterfeit, at least it looks like the picture on DeWalt's website.  It's heavy, and came with a light oily residue on it which I took to indicate being new.  The box was unopened.  Everything looks right, it just isn't doing the job I bought it for.  I'm using it with a 10" impact extension, if that makes a difference.  What could the problem be?
