Just put together a new GT and have a O.S. .12 CV-X for it. Just
finished everything today. Trying to get it to start. I set that one
needle (forget the name of it & booklet is outside) 2 turns out. I did
not mess with the other one. Carb had opening of 1/32 at idle as
specified in book. It will start if I give it a little juice but when I
let it off it dies. Is this cause it's new or do I neeed to adjust the
other screw?

  It's too rich, you need to1/8 turn it in not out.  Then keep turning it 1/8
with every tank until you get more power.

We need more info, specifically, which needle you moved. I'd get the
instructions, follow them exactly for reseting the low end (mixture)
needle, set the high end (the tall, brass-sleeved one) at what the
instructions say for breaking in the engine (which is crucial), and
start over from square one. Also, the clutch on your GT, does it use
springs on the shoes? You may want to set the idle a bit higher if they
use no springs, as this will want to stall the engine at lower RPMs,
since they are trying to engage. Try re-doing it per the instructions,
and if it still won't work right, post here again, and tell us
everything you did/tried...we'll get it runnin' fine:)

make sure your throttle stop***(small with spring on outside) is in
far enough, this adjusts the carb barrel so that even at full
brake/throttle closed, there is still enough of an opening to allow the
engine to idle. specs for that opening should be in the OS and/or GT
booklets.
luvya!

no i think he is incorrect. 2 turns is a good starting point on the CV,
after that its only fine-tuning.
luvya
no really

Make sure that you use the piece of wire that came with your kit to measure
the carb opening.(if you didnt throw it away already)  Its about 2 inches
long and is the perfect thickness for setting the carb opening.  Its
probably with the ton of other spare pieces you had leftover.  Make sure the
carb stop***is set so that when you apply your brake, it doesnt close
the opening.  You may also need to rev it a little(dont go crazy because you
will ruin the engine) for a few minutes to get it warmed up.  It should idle
easily if the gap is set right.  The needle should be two turns out and you
shouldnt need to touch the mixture***until your near the end of your
break in.  Follow the instructions in the engine manual.  You may also want
to check the fuel line for leaks and the line from the pipe to the tank.  If
air is escaping, it may not be forcing the fuel into the carb when idling.
On an unrelated note, get some after run oil to put into the engine after
each run.  It will prolong the life of your engine and keep it running
smoothly.

that 1/32 figure is a ballpark figure.  Adjust the idle open amount to
a nice idle.  Make sure that the idle speed is lower than the clutch
engages though.

When your engine is running rich (IE break in), the idle open amount
will need to be a little different, than when it is fully broken in
and mixture adjusted correctly.
