yves, I am attaching what I use (courtesy of a Member here), but there are also posts about this topic if you do a search.

I have 6deg advance.

I guess in higher revs you may go up to 38deg total if it is not pinging, I left it a bit lower.

Best is to go through search and related posts.

Which is correct if you have the vacuum advance disconnected. This is what the factory recommended. Once set you then re-connect the vacuum advance and confirm you've now got 38°.
