Description

Over years of constant petrol exposure and engine heat, original plastic floats can become heavy, porous, or completely cracked. When a float fails to rise properly, your carbs will either flood the motor with raw petrol—causing heavy fuel smells and hard hot-starting—or completely starve your main jets at high engine speeds. Swapping out your broken or missing parts for this high-quality aftermarket Hyosung carb float is a vital step in any professional clean-out. It guarantees that the fuel line supply shuts off exactly where the factory intended, ensuring a reliable power delivery during your next workbench restoration project.

🔧 Install Tips

  • Set Your Heights Accurately: For most traditional v-twin carbs, you should aim for a total float height measurement of approximately 7mm. Use a caliper to measure from the flat aluminum casing gasket face (make sure you lift the paper seal off first) down to the very top edge of the black plastic wings.
  • Use a Gentle Touch: If your alignment is off, take a small pair of pliers to carefully bend the central metal tab that makes contact with your needle valve pin. Never apply tool pressure directly onto the soft rubber tip of the valve itself or you will ruin the seal face!
  • Check Your Hinge Pins: Make completely certain that your straight pivot pin is clear of gummy fuel varnish or green scaling. The plastic wings must pivot smoothly up and down under their own weight without catching or sticking against the pillar towers.
📧 NOT SURE HOW TO ALIGN YOUR PLASTIC WINGS WITHOUT TEARING THE GASKETS? If your bowls are actively leaking from the overflow snouts or you want to verify your float height measurements before closing your casing, you can upload a crisp photo of your open carbs on the forum to get an instant check from other builders.
