Help! I need BS34CV Air screws

[vanzantfrynd]

I'm having a terrible time getting the air screws out of my BS34CV carbs. I took the caps out and it appears they used glue under the caps. If anyone has experience with this problem, please let me know.
Another question is where I can purchase new air screws. Bikebandit doesn't have them and I can't seem to find them online.
Any help would be greatly appreciated!

Hit the screws with PB Blaster, then heat the carb body. Make sure your screwdriver fits snuggly too. Grind the tip as necessary. If heat doesn't loosen them right away, use more heat and more spray. Turn the screw both ways until you get it to move. Once it does, keep going. Take your time and the screw will come out. Rush and you are in for trouble.

Good luck

That is going to be a neat trick, because the BS34 carbs don't have air screws.

What you do have is "mixture screws", and yes, they can be a pain to get out.

As Nessism suggested, PB Blaster and some heat usually works. If the slots get buggered up and can not be used, a large cut-off wheel in a Dremel can cut a slot down the entire tower and put a new slot in the top of the screw. If it gets to that point, let us know there are some pictures in the archives we can toss your way.

Make that "pilot screws" Steve. Didn't we have this discussion one time before?

True enough, Ed, but it's still not an "air" screw.

Wow you guys are on it...

Thank you! I have the "mixture screws" soaking in penatrent for the last 2 days. Heat was my next idea as well. I found this site: http://www.heidentuning.com/p/28/242...de-needle-clip
as I'm pretty sure that my old screws will not be usable. They're a little pricey, but at least they carry them. I'll get back to you when I get them out...

BTW NESSISM-
That's a very interesting carb set up on the Honda in your pics! Cool...
