I had recently purchased an ST1100 and on the way home with the bike I had the strong smell of gas.. I have found that the ear for the idle adjustment screw had been silly puddied back together.. Can the idle screw tab be TIG weldid back on to carb #4? What would be the best way besides buying a carb set?

Is there any way to provide pics of what you have going on? It'd be easier for us to help if we could get a look at your problem.
I will try to get pictures tomorrow... I have the carb set off of the motor so I can get to it... when the ear that holds the idle adjustment screw broke off it left a hole in the side of the fuel bowel and you can see the float on carb # 4. someone had used an epoxy or some type of putty to seal it. It seems what ever they used was not fuel resistant..
I was looking through pics I had taken of my carbs last time I worked on the bike, is this the tab your talking about?
If that's it, I would find a local welding shop that could TIG weld it back together. Such a small job would be easy for a good welder.

That is it. I wasn't sure if it could be TIG welded or not... i am gonna take the cover off and remove the float.. the hole is about the size of a dime... should be a quick fix...
I don't see why it couldn't be welded. A good welder will be able to make it good as new.
Thank You.. I'll let you know how things go...

The alloy used on these carbs is difficult if not impossible to weld. I speak from experience from many years ago attempting to repair a cracked float bowl. It was on a Mikuni carb though. I guess you could say nothing ventured nothing gained however.
I have seen many used ST1100 carbs for sale on Ebay at fairly reasonable prices if the welding does not work.

I tried the welding and it did not work.. The idle adjustment tab just crumbled to peices.. i wound up using VersaChem Magnum Steel Epoxy stick to seal the hole in the fuel bowl. Figured I can make a bracket to mount the idle adjustment screw and use the screws for the fuel bowl to attach it..
Man, that's a hell of a hole! Sucks the welding didn't work. Looks like you figured out a good solution for cheap. I wonder how the PO broke that off in the first place?!?

Me too, probably during an attempt to pry the carb bank out the rubber boots... I wouldn't trust a glue solution (a serious issue if that fails while on the road...) and seek a case on Ebay or brakers avail.
I'm not sure how he did it either. The only thing I can think of is instead of using the idle adjustment screw they tried forcing the throttle closed. I'm considering using some 1/4 inch brake line or copper tubing to build a bracket that I can attach using two float bowl screws to attach it. In theory it should work. I will keep up with pics of progress.
fuel bowl after Versa Chem epoxy compound..
I got the bike back together last Tuesday. Waited till I got back Thursday night to finish all the fairing. Epoxy is hard as a rock.
Put about 150 miles on it Friday. And cleaned it all up after I got tags.
Here are the updated pics.
