Briggs & Stratton jet needles are genuine replacements made from top-quality materials, like aluminum and stainless steel. They'll help you to maintain the proper air/fuel mixture for the best performance—by controlling fuel when you open up the throttle. Available for alcohol and gasoline fuels, Briggs & Stratton jet needles are sold individually (needle only), or with clip and retainer. Order the jet size needed for your application.
