The throttle cable is not connected to the slide, it operates the butterfly which is located on the engine side of the carburetor. As the butterfly is opened more air is able to flow in. This changes the air pressure in the bore, pushing up the diaphragm and drawing the slide and tapered needle with it. Similar to the cable slide carburetor, when the needle is raised more fuel is supplied and as the butterfly opens more air is added to the mix.","brand":"Monster Scooter Parts","offers":[{"title":"Default Title","offer_id":44337374331042,"sku":"P33-4381","price":29.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6943\/0690\/files\/p33-4381_6_1.jpg?v=1774894391","url":"https:\/\/monstorscooterparts.shop\/products\/pd42j-a-carburetor-for-the-yamaha-yxr660-rhino-660-atv","provider":"Monster Scooter Parts","version":"1.0","type":"link"}
