Best place to purchase parts? To help keep it searchable please limit reply to best price, selection, customer service, rare parts, etc! I’ll try to update original post and help keep it organized. I propose a format of Consumables (chains, bars, oil, etc): Husqvarna parts: Sthil parts: Chainsaw parts (not Sthil or Husqvarna): General small engine: Automotive parts: Rock Auto
Might be stepping on a few toes here but I'd stay away from "The little red barn" if they are still in business. His aftermarket stuff doesn't fit and he doesn't offer much support in correcting problems.
I have used " partstree" in the past. Their site has all the exploded diagrams that is a big help. Not sure if they are the cheapest but seemed to have a good selection.
I’ve had good luck with Jacks Small Engines. I’ve placed a few orders with them over the years and they’ve been good to me. Lawn Mower Parts | Small Engine Parts - Jacks Small Engines
I forgot about Jacks , they also have all the exploded views as well. I have never used them but a coworker did order from them a while back and he didn't complain so I guess that's a good thing.
For Husqvarna parts , Husqvarna Parts Distributors – Genuine Husqvarna Parts & Accessories They have ipl’s for most everything husqvarna makes . I also like ereplacements , and chansawr.com .
One place that I think is underrated is Northwoodsaw.com for aftermarket stuff. Meteor pistons are probably the best aftermarket piston.
