Injector looks fine even under a magnifying glass, fair bit of dirt and crud in the threads and in the threads in the well.
Managed to clean them out OK without too much going down the hole!
So my question is, which is the correct way to install the flame trap.
Yes I looked at the orientation of the old one before removing but just to make absolutely sure I put the new in the correct way......

Can somebody please tell me 100% the correct orientation for the new trap?
Waiting with bated breath.
