First time I have used a copper one and it was untight right away. Probably it was not heated correctly.
Will give it a try again later as they can be reused.
Actual gasket is from an Athena gasket set.
I think I have to let cylinder and head to be face-grinded (maschined to be flat and parallel).
[Very hard for me to describe that in english language, pardon for the mistakes in that sentence]
Will not start that action before our trip.
Some steam cleaning will help 😉
Cheers, Michael
