Hi Jim

In the diagram below 10=3Dretaining clip, 11=3Do-ring, 11a=3Dadjusting screw=
, 12=3Dneedle locking screw, 13=3Dmetering needle

You only have 2 1/2 turns from full lean (screwing the adjusting screw all t=
he way onto the needle) to full rich (screwing the adjusting screw all the w=
ay out of the needle).
At full lean the adjusting screw will stop turning because it is screwed all=
 the way into the needle, at full rich it will keep turning because it is sc=
rewed all the way out of the needle.=20

Make sure the needle locking screw is not screwed in far enough to lock the n=
eedle into position, but is screwed in far enough into the slot in the top o=
f the needle to keep the needle from rotating. The top of the needle has to b=
e able to slide up and down but must not rotate. The adjusting screw will mo=
ve the needle up and down as it is screwed into and out of the top of the me=
tering needle. If you have screwed the adjusting screw counter clockwise mor=
e than 2 1/2 turns, the adjusting screw is not engaged with the needle - pre=
ss down really hard with the adjusting tool when you turn clockwise to try a=
nd re-engage the adjusting screw with the needle.
=20
You should not be pulling hard on the needle or twisting the needle - there a=
re no =E2=80=9Cspring positions=E2=80=9D - you don=E2=80=99t want to twist o=
r break the spring.
With the adjusting screw screwed all the way out and the needle locking scre=
w removed, a gentle pull on the needle should remove the needle from the dam=
per assembly - if it does not come out easily, it may be too stuck to be adj=
ustable - soak it overnight with penetrating oil and try again.

Hope this helps.

Cheers,
Jack Mc

I'm my case on my Stag . Same carbs. The star washer was missing so the
needle didn't move up or down. Maybe ur star washer is not fully seated.
