Set Contains: 1 x Part Number 790849 Air vane spring Review: 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. Review: Pièce Originale - Excellent.

I have a toro ezy walk behind with auto choke. It works on the choke. **Q: what is the difference between b&s spring #590740 and #790849 ?** A: The 590740 is OEM (original equipment) & the 790849 is a replacement part. Probably just as good either way.. so take your pick you’ll be just fine… **Q: This appears almost identical to the springs on the hinge or folding mechanism of a scooter, anyone try em?** A: How about you try it and tell us how it goes. **Q: I lost the spring that controls the outermost throttle plate. I couldn't really tell from the parts list. Is this the right part?** A: It looks like the right part, but there's different lengths of springs that can fit there. You'll have to measure between the throttle plate and the governor lever which the spring goes on to. Then get the right length spring that will have tension on there. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Genuine OEM Part. Worked as described. *by O***H on 2 July 2026* Genuine OEM Part. Worked as described.
