This allows the inlet jet to open and you avoid the lean bog that often happens with Stock carbs on Tuned 32 Reed, 34cc, Taylor 35cc, OBR 34,35 38cc \u0026amp; FJ350RC Engines for example. Works very well when adding the upgraded Bonehead Carbon Reeds to your engine too.\u003c\/p\u003e\n\u003cp\u003eThis is the stock supplied Walbro Upgrade as used by their R\u0026amp;D Dept in the 1242 and 1257 Upgrade carbs, best you can get.\u003c\/p\u003e","brand":"Taylor RC","offers":[{"title":"Default Title","offer_id":62971023655299,"sku":null,"price":3.79,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/0550\/3978\/files\/genuine-walbro-aftermarket-pop-off-spring-for-990-1107-fujiwara-14mm-15mm-carbs.png?v=1792751619","url":"https:\/\/taylorrc.co.uk\/products\/genuine-walbro-aftermarket-pop-off-spring-for-990-1107-fujiwara-14mm-15mm-carbs","provider":"Taylor RC","version":"1.0","type":"link"}
