The choke thermostat regulates the electric choke plate as the engine warms, adjusting air\/fuel mixture during cold starts and warm-up so the carburetor transitions smoothly to normal operation. Sierra 18-7665 carries a white housing finish and an adjustable design, allowing the choke setting to be tuned to the engine's starting characteristics. Its compact housing measures 2.25 inches deep by 2.25 inches wide by 1.25 inches high and the unit weighs 0.14 pounds. The Sierra 18-7665 directly replaces OEM number 809066 and is intended specifically for Weber 4V carburetors equipped with an electric choke, making it a straightforward drop-in replacement for a worn, sticking, or failed choke thermostat on this carburetor type.\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 18-7665\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces:\u003c\/strong\u003e 809066\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Weber 4V Carburetors with electric choke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 2.25 inches D x 2.25 inches W x 1.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Feature:\u003c\/strong\u003e Adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282277185\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWeber 4V Carburetors with electric choke\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e809066\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-7665 choke thermostat fit?\u003c\/strong\u003e The Sierra 18-7665 is designed for Weber 4V (4-barrel) carburetors equipped with an electric choke.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the Sierra 18-7665 replace?\u003c\/strong\u003e It replaces OEM number 809066.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7665 choke thermostat adjustable?\u003c\/strong\u003e Yes, the 18-7665 has an adjustable design so the choke setting can be tuned to the engine's starting behavior.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-7665 choke thermostat?\u003c\/strong\u003e It has a white housing finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-7665 weigh?\u003c\/strong\u003e The 18-7665 choke thermostat weighs 0.14 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the Sierra 18-7665?\u003c\/strong\u003e The housing measures 2.25 inches deep by 2.25 inches wide by 1.25 inches high.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-7665 work on a Rochester or Mercarb carburetor?\u003c\/strong\u003e No, the 18-7665 is built specifically for Weber 4V carburetors with an electric choke; Rochester and Mercarb 2V electric-choke applications use a different Sierra part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-7665 a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-7665 is a Sierra-branded choke thermostat, sold under Sierra part number 18-7665.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when ordering the Sierra 18-7665?\u003c\/strong\u003e Ordering the Sierra 18-7665 gets you one choke thermostat unit for a Weber 4V electric-choke carburetor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Sierra 18-7665 replace a stuck or sticking choke thermostat?\u003c\/strong\u003e Yes, replacing a worn or sticking choke thermostat with the Sierra 18-7665 restores proper electric choke operation on Weber 4V carburetors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7665 use electricity to operate the choke?\u003c\/strong\u003e Yes, the 18-7665 is built for the electric choke system on Weber 4V carburetors, not a manual choke setup.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988386099419,"sku":"SIE-18-7665","price":99.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sie-18-7665_lg__85018.1558141472.500.750.jpg?v=1785188477","url":"https:\/\/www.goodvibesmarina.com\/products\/choke-thermostat-for-rochester-mercarb-2v-carburetors-with-electric-choke-replaces-70125a1-sierra-18-7665","provider":"Good Vibes Marina","version":"1.0","type":"link"}
