The mechanic that works on my BSA A65L (when I get into a jam) In stalled a pair from the Bonneville Shop. He seals petcocks with Permatex Aviation Gasket Sealer and lets it cure for a day or two. The sealer is dark brown
..
This guy restores many bikes for Baxter's and just restored a Velocette that came in 3 large crates. I have confidence in him.

So far so

Apart from the corks the tap body wears, clean ,then shine a light and put yer specs on, look hards at the tap body bore where the cork rubs, is most of the plating still there, if so , it might work, are there deep scores, obvious wear , less than 50 % plating, its worn, even the best cork will struggle.
Once upon a time I too admired the elegant simplicity of the original taps. that lasted 20 years, Mine are all worn out. I was badly prejudiced against them when one one of the taps( reserve) pulled off in my hand , had to ride with my thumb over the hole. I wont have them now.

Good luck with that! I guess that's the price you have to pay "correct looks".

Boil it in water then squeeze All the water out. Then push it in.

The fuel will cause the cork to shrink, the water will keep it lubricated yet sealed.


Now let’s all have a beer beerchug

Soaking in hot water softened the cork, but the fit was still too tight.

Then I tried soaking in fuel. That helped. I was able to fit the plunger into the bore. The action was very tight at first but seemed to improve with soaking and movement. The petcock assembly's are soaking in fuel for now. Time will tell if they leak.

Steve: Are you referring to sealing the threads?
