Weird because this is how the power jet tube should look. The road race carby has the power jet nozzle angled up to end in the centre of the carby bore.

In my experience, you'll go a fair bit leaner on the pilot, but main jet will be about right.

Currently jetted 45 pilot 178 main 1369 needle middle clip.

Started 1st kick idles ok but still seems to load up a little
Gets a bit of "gunn" every few seconds like it has a bit of unburnt fuel. Going to try a 42 pilot.

Nathan I think your tip was spot on.
