To soak or not to soak...
« on: January 12, 2021, 07:38:15 PM »
This is way off topic for an SOHC forum, but there is such a wealth of knowledge, Ill ask anyway.
I have a push pull type fuel tap on my 1948 Francis Barnett. I am renewing the corks washers that sit above and below the push pull bit, and act as seals. I have researched on line and there are numerous different views. Some say boil the corks before fitting, some say soak in petrol or water. Others say just fit them as they are.
Does anyone have a view on this? Cheers Harold

if they are new corks and in the fuel system, i would suggest soaking in petrol.  i boiled my old panther corks from the clutch plates years ago, but that was to try and make them softer as they go hard and shiny with use. but then again, would they have been soaked in anything at the factory? your choice, i'm afraid!  nice bike though

From experience I would warn against soaking them first as they expand and can then be difficult to fit.

Put them in dry, then switch the petrol tap on and let them soak in place.

Hope this helps
