i have the cv34's that WG rebuilt. but the #2 doesnt seam to be giving out any fuel. its getting spark, the cylinder has good comp, but the plug looks like its just a little wet but thats it.
ok just took it for a ride. once you get past half throttle the thing takes of line a bat out of hell.
so it has to do with the idle jetting i am guessing

like i edited above. once you get to 1/2 throttle it takes off like a jet.

When starting the cold engine with choke applied, is there combustion in #2 cylinder?
Do these carbs have a separate enrichener circuit or a true butterfly style choke?
Good Luck!

1) remove the tank
2) Remove the drain plug from the bad carb.
3) remove the pilot needle from the same carb.
4) fill a sirring with some gas
5)seal sirring to pilot screw opening with an o ring or small hose.
6) In 2cc increments squirt into the screw opening
7) Repeat about 3-4 times.
This should clear any obstruction, and flow it out the drain hole.
Reinstall pilot screw and open to the correct amount of turns.
This trick will work if the hole was clogged after the rebuild. It most likely not work if the rebuild was not done properly.

Look into that end of the carb which connects to the motor.
Open the throttle flap and look up. First in is a tiny hole which is from the air mix screw directly above. Easy to spot. Just beyond the throttle flap and further in from the air mix hole are the transition holes. 3 tiny holes. I use a very fine bent wire to poke them clean. The smallest piece of dirt will block them and while the bike will start ok with the pilots clean it will run like crap in the lower rpm range and only run proper at >3000rpm.
I spent an entire summer tearing my hair out before I found these transition holes. Could be the source of your problem ?
Just reading your post again and wondering if you are thinking the pilot jet screw is on the outside top of the carb closest to the engine. Thats the air mix screw and it should be turned out 2 turns from lightly seated. The pilot jet I was talking about is only accessible from inside the carb

Check the others to see how many turns out they are, and they should all be close to the same. Put your #2 on a setting similar/average of the other carbs.
Out = more fuel mixture/In = less.
...ride on
Good luck!
