air screw broke in carb body

I am rebuilding my carbs and on one of them the air screw broke off just below the threads and the rest is stuck in the carb body. I had it run through an ultrasonic cleaner hopping that would loosen it and it would come out,no luck.
Does anybody have a solution or has run into this?
I do have a line on another bank of carbs off a friends parts bike but would like to save this one if I can.
Thanks
 
If you have an "air screw", that means you have VM carbs on a '79 or older bike. Not sure what it would take to get that screw out.

If you have an '80 or newer bike (or a twin), you don't have "air screws", you have "MIXTURE screws" (more-properly called 'pilot' screws).

I have seen some of these stuck in the threads, but never broken below them.

Please identify the carbs, and also which one you need, as they are position-specific.

The number on the side of the carb is 45170 , the reply with the link is workable if I remove the puck behind the butterfly valve in the throat of the carb.
 
Page 10 of the carb cleanup series shows exactly what I have, that is why I called it an air screw.
 
A butterfly and an air screw on the same carb? What is this some kind of Honda or something?
 
We need to know what model/year the bike is. If it's a 1980 or newer bike I may have a replacement carb body for you.
 
Instead of muddling through all the technical terms, just tell us what bike you have. :-\\\

Any further attempts at help will be useless until we know what bike we are talking about.

The ultrasonic did not work and it tums out the carbs my friend has are off a 1979 so the y won't work, again thanks for all the help guys sorry about posting the wrong info
 
Sometimes the tips can be felt thru the hole if you run your finger down the bores. If you can feel the tips take something and press them back in and see if that helps pop them out. That and the fine tip of the home made removal tool may be the magic mix.
 
yep, tried that,no joy, the guy who did the ultrasonic dip (very experienced guy) tried too but no luck. I am afraid this one is toast. I think these carbs were also used on some other bikes of the same vintage/ 550 or 650 ?
 
Measure the bore at the engine side....should be 32 or 34 MM. Then get then corresponding carb in that bore size. Carbs are referred to as 1, 2 ,3 or 4. #1 being the carb to the left as you are setting on the bike.
 
I have a spare #2 carb body for a 1982 GS850 (BS32SS) cleaned and ready to go. If you're interested then PM me about the specifics. Now if you post a pick or describe exactly where the "air screw" that's broken is, I can include that as well.

I figured it was a terminology issue. Just wanted to make sure he wasn't talking about the pilot jet or something else. You never know unless you ask.
 
Yep, wrong terminology on my part, it is the mixture screw. Thanks for working through this with me guys.
