I bought a set of carbs on ebay because I needed the carb #2 body. As I was pulling the #2 carb apart I found that I could not get the throttle valve out. The lid is removed and the diaphragm is not stuck, but the valve won't come out. It moves up and down about a quarter of an inch and spins freely inside the carb body, but when I try to pull it out it feels like it's getting stuck on something. All the other throttle valves move freely and I have removed one of the others just to make sure it would come out. Does anybody have any advice on what to try to get the throttle valve out?

Are you trying to remove the throttle valve or the slide?
They are NOT the same.
The throttle valve is the butterfly on the shaft near the outlet of the carb.
The slide is below the diaphragm and is the moveable part of the variable venturi, not the "throttle valve".

Gas and corrosion have seized around the needle and the jet. Take off the bowl and soak it all with some penetrating oil a few times a day till its good and soaked in.
Then take an old tooth brush and grind the handle flat like a screw driver blade. Use blade to gently pry between the slide and the carb body.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.Comment

I was trying to take out the slide. Sorry, I may have gotten the terms mixed up. I was able to get it out. I determined the needle was stuck to the jet and the jet was jammed on something inside the body. I was able to knock the jet out and the needle and slide came with it. They are still stuck together, which would normally be a problem but I wasn't planning on using those pieces anyway so I'm not going to worry about that.Comment

it should not spin inside the carb. there should be a pin in the carb which locates in a slot in the slide, which prevents it from turning.Originally posted by TylerM View Post1978 GS1085.
