When one gets clogged or worn, you’ll notice it right away—rough idle, stalling, or sluggish response off the line. I’ve cleaned plenty, but sometimes replacing it is the only way to get things running right again. When it’s dialed in, the engine idles smooth and transitions clean into throttle.\u003c\/p\u003e\n\u003chr data-start=\"503\" data-end=\"506\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"508\" data-end=\"523\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"524\" data-end=\"926\"\u003e• \u003cstrong data-start=\"526\" data-end=\"552\"\u003eLow-Speed Fuel Control\u003c\/strong\u003e – Regulates fuel delivery at idle and low throttle for smooth operation.\u003cbr data-start=\"625\" data-end=\"628\"\u003e• \u003cstrong data-start=\"630\" data-end=\"653\"\u003ePrecision Sized Jet\u003c\/strong\u003e – Calibrated at 37.5 for accurate fuel-air mixture in carbureted systems.\u003cbr data-start=\"727\" data-end=\"730\"\u003e• \u003cstrong data-start=\"732\" data-end=\"757\"\u003eOEM Fit and Threading\u003c\/strong\u003e – Installs cleanly into the carburetor without modification.\u003cbr data-start=\"818\" data-end=\"821\"\u003e• \u003cstrong data-start=\"823\" data-end=\"850\"\u003eImproves Idle Stability\u003c\/strong\u003e – Helps eliminate stalling, hesitation, and uneven low-speed performance.\u003c\/p\u003e\n\u003chr data-start=\"928\" data-end=\"931\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"933\" data-end=\"963\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"964\" data-end=\"1201\"\u003eDesigned for Yamaha outboard engines equipped with carbureted fuel systems that utilize a pilot jet for low-speed fuel control.
