The Tillotson Adjustment Screw Packing or O-Ring seals the adjustment needles to prevent fuel from leaking out of the carburetor.
This Packing or O-Ring fits on the High and Low Side Adjustment Needle for most Tillotson Carburetors except for the HD Models, which only fit the Low Side Needle on the HR Carburetors.
These O-Rings need to be replaced every 8-10 races or during a complete rebuild. The O-Rings are included in our EC Pro Rebuild Kits but do not come in Tillotson OE Kits.
