Yes, that pin keeps the needle jet from rotating and the open end of the shroud sticking up into the airflow facing forward.

But to be absolutely clear, that's not the pin which we were originally talking about, right? The pin 71DT250 first mentioned is the pin in the barrel, which fits into the groove in the slide. Just so we don't confuse someone still thinking about that pin...

Or am I confusing this with another thread? But rereading 71DT250's post right out of the shoot, I think we were talking about the slide in the barrel.

It might be a good idea to remove the needle jet while you
tap it in . In case it has turned whilst locating pin was out .
You could just remove the setter , and you'd see if the locating
slot in the needle jet still aligned with the pin .

saved from a huge read - thanks!

Mr Mothersbaugh - this is in fact was the subject pin, which some helpful nice person suggested could be the slide locator...but then again I cannot remember what I had for breakfast or how many drinks I had tonight.  It is not slide locator,  mine still there and is shaped like the cross section of a cylinder with hemispherical ends. Would really suck for engine to eat this up, I bet the clever Japanese engineers have it pressed in from the outside since it appears to have a flange 

It's def the "jet, needle jet" locator, I am going to blow this thing out real good again, check everything again and keep whack a moleing 

thanks all

To add to what Swoop said, the only time I saw one of those come out was when someone (

) accidentally had the jet rotated backwards and tapped hammered it into place with a hammer and a hardwood dowel. 

It was a long time ago but I think I ruined that carb.

Thanks! I just didn't want someone who had never been in a carb before to get confused...

while I fancy myself as a relatively competent mechanic, I did have an "issue" removing the jet, needle jet and did tap it ever so gently in the wrong direction.  Still runs out of gas at any speed without choke so back to the bench, this time maybe without a drink.

I will spare you the clutch issue, which clearly was PO related
