This set provides you with the parts necessary to convert an existing O.S. .91HZ or .91HZ-PS engine to the newer fuel pressure regulated .91HZ-R version 61E-R carburetor. This system pressurizes the fuel delivery system, allowing for a more reliable, and more powerful setup. Also, a pressurized fuel system helps to prevent the fuel magnet and fuel line from getting corroded by the dirty exhaust gasses, which is a problem found in systems that use muffler pressure. \u003c\/span\u003e\u003c\/p\u003e","brand":"OS","offers":[{"title":"Default Title","offer_id":53217261551889,"sku":"Os72512000","price":249.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/5120\/3345\/files\/os72512000.avif?v=1772821982","url":"https:\/\/advancerc.ca\/products\/o-s-91hz-r-conversion-set-72512000","provider":"Advance RC \u0026 Hobbies","version":"1.0","type":"link"}
