I don’t see how this item could be new old stock or genuine Stihl parts. It has no Stihl part numbers of branding anywhere on it, and it does not fit properly on my saw. 056 is listed as a compatible model, but the air filter opening is too small and completely inhibits the choke plate from operating. I think it’s a cheap reproduction and the item’s title is inaccurate. Would not recommend buying, especially at the price of $39 + shipping.
