High speed needle issue

During my engine break in, I saw my HSN was coming loose from the vibration.

Took it out and I can see why.
The o-ring is shot. Hardly any left. Lol.

So I managed to source some o-rings.

Bought some spare as well. Lol.

The code for the o-ring is 006. Not sure this will help anyone as i guess no one has this engine anymore.

Now I can get onto the tuning.

So here is me replacing the o-ring and giving the needle a clean.

Screwing it in, it really feels nice and snug. No more coming out.
