Hello everyone, I'm in the process of rebuilding my first engine and was wondering how you guys remove the carbon build up on/around the valves ( if its even necessary to remove all of it ). I don't want to be too rough as I know these parts are delicate for clearances, especially around the seats. I used scotch brite for a while and it doesnt seem to touch the mountains of build up. Here are some pictures:
I know carbon is going to build up again which is why im wondering how clean I should get it while im here, and how to clean this off if needed.
Thanks
