The rubber tips on float needles will age and form a groove that prevents proper sealing and results in a flooding carburetor. OEM float valves will often be worn even faster by ethanol blended fuels that are so much more common now. Replacement float needles allow you to repair a leaking/flooding carb at a fraction of OEM cost. If your float needle has a groove from the seat or leaves behind black lines when rubbed against a shop towel, the rubber has deteriorated and the needle should be replaced. We suggest using a cotton swab in a hand drill with light polishing compound to polish the seat to remove any corrosion or light pitting when installing a new needle; toothpaste is great if you don't have valve lapping compound or chrome polish.
