Genuine OEM Part. Worked as described.
Genuine OEM Part. Worked as described. Just so you know, This little part was the missing link to whether the carburetor worked or not. So if your lawnmower is not turning over on first pull, even after a complete cleaning/overhaul or complete replacement as I did, it can very well be because of something as insignificant and easier to overlook, correct tinsel tension of this little spring. I had an incorrect spring that its tension was to tight and strong, that it did not allow any or enough of a give for the choke of the carburetor to open and allow some air in so it can turn over. So the right thinniss and tension for the choke to work as intended is vital as I discovered. Briggs and Stratton motors are truly very precise and finicky. So you really cannot cut corners using non-OEM parts. For some parts, it can really make the difference, and this Air Vane Spring is definitely one of them.

Ayant perdu l'ancien, il est parfait
Pour une debroussailleuse 3 roues. Remplace parfaitement d'original. Depuis j'ai rajouté une protection devant le moteur, car les fougères coupées m'ont tordu ce ressort (l'ancien). Merci. Revoir un délais pour le port, être patient.
