In these carburetor systems, the choke pull-off is the component that reacts to intake vacuum and pulls the choke plate open to the correct partial-open position once the engine starts, preventing an overly rich mixture during warm-up. As the engine and carburetor age, a worn or leaking choke pull-off diaphragm can cause hard starting, stalling, black smoke, or a choke that stays closed too long (or opens too soon), so replacing it with a properly matched unit restores correct choke plate timing and smoother cold starts.\u003c\/p\u003e\u003cp\u003eThe Sierra 18-7667 is manufactured to fit Rochester 4V carburetors and directly replaces OEM number 1397-8582. It is sold as a single choke pull-off unit and installs in place of the original component using the existing carburetor mounting points.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7667\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Choke Pull-Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Rochester 4V carburetors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 1397-8582\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.17 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282277208\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eRochester 4V carburetors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1397-8582\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7667 choke pull-off fit?\u003c\/strong\u003e The Sierra 18-7667 is designed for Rochester 4V carburetors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-7667 replace?\u003c\/strong\u003e It replaces OEM number 1397-8582, so it is a direct-fit alternative to that original part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7667 a genuine OEM part or an aftermarket replacement?\u003c\/strong\u003e The 18-7667 is a Sierra-branded aftermarket part manufactured to replace OEM number 1397-8582 on Rochester 4V carburetors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7667 choke pull-off weigh?\u003c\/strong\u003e It weighs 0.17 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Sierra 18-7667 made from?\u003c\/strong\u003e It is constructed from alloy steel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-7667 choke pull-off?\u003c\/strong\u003e It has a white finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does a choke pull-off do on a Rochester 4V carburetor?\u003c\/strong\u003e A choke pull-off responds to engine vacuum after startup and pulls the choke plate open to a partial position, preventing the overly rich fuel mixture that would otherwise occur if the choke stayed fully closed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are signs the choke pull-off needs to be replaced?\u003c\/strong\u003e Hard cold starting, stalling after startup, black exhaust smoke, or a choke plate that opens too early or too late can indicate a worn choke pull-off like the 18-7667 needs replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many units come in a package of the 18-7667?\u003c\/strong\u003e The Sierra 18-7667 is sold as a single choke pull-off unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7667 work with 2-barrel Rochester carburetors?\u003c\/strong\u003e No, the 18-7667 is specified for Rochester 4V (4-barrel) carburetors, not 2-barrel models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-7667?\u003c\/strong\u003e The UPC for the Sierra 18-7667 choke pull-off is 808282277208.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988385837275,"sku":"SIE-18-7667","price":76.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sie-18-7667_lg__56831.1558141555.500.750.jpg?v=1785189015","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7667-choke-thermostat-for-rochester-carburetors-with-divorced-choke-replaces-71464a01-71464-72625","provider":"Good Vibes Marina","version":"1.0","type":"link"}
