The needle and carrier (should) just pull out as a unit after you have
unscrewed the adjustment all the way.  You'll need a mixture wrench (the
long hex wrench with the aluminum piece that rides on the shank) to undo the
adjustment.

Then you can use a suitably sized rod (I used an unsharpened #2 pencil) to
tap the adjusting screw and it's retaining clip out the top.  I found it
easier to hold the piston and rap the end of the pencil against the bench,
but either way should work.

This diagram is from the TR6 workshop manual, but matches perfectly the
carbs on my 71 Stag.

Thanks.  I actually found my old mixture adjusting wrench and that fit of course.
Pretty easy once I got into it.  The buckeye triumphs article is very good.  I still could not get the needle out after backing off the adjustment all the way and taking the setscrew out.  But, some pentrating oil, reassembling it and running the adjustment back and forth a few times finally loosened it up and I got it out.  Similar with tapping out the adjustment screw.  Would not budge.  Once it broke feee, it came out easily, but took a bit of persuasion at first.  I guess neither had been moved in 45 years... So 1 carb done and one to go.  Thanks for the help,
Frank
