If it has the brass plunger tap, the seal/s should be replaceable.

If it is cork, and there's a slotted screw set in the pull knob, replacement corks are available. Otherwise it will have two o-rings, and these are also available. Check the ODK Online Shop for both.

I'd grab a spare set of the nylon throttle shaft gears too, as these are getting hard to find.

Cheers,
