(quoted from post at 17:39:37 07/20/21) How is it damaged? I had one break off. I was able to remove it with a dental ultrasonic device.
(quoted from post at 18:58:40 07/20/21) The idle jet is 10-32 thread
No. 21 tap drill 0.1590
5/32 is 0.1562, still safe if your hole is drilled exact center.
Problem with an ease out is that in order to grab it expands the soft brass and makes it stick in the threads even tighter.
Heat does help. Normally heating the casting to 450-500F but if there is rust involved 600F is better. Something to do with rust giving up some oxygen. Let the casting cool back to room temperature naturally and you will find any brass parts much easier to remove.
I am wishing you luck!(quoted from post at 20:28:41 07/20/21)(quoted from post at 18:58:40 07/20/21) The idle jet is 10-32 thread

I didn't heat it that hot. The 1/8" hole is slightly off center. I did order a #21 drill and a 10-32 tap and some round swiss needle files. Perhaps I can file out most of the brass and use the tap to clean the brass out of the threads. Wish me luck!
Thank you.

In my experience, the best way to get them out is to boil the carb body in hot water,
so it is hot, and then turn it out before the ears are broken off.
That's not always an option, of course, but it does work well.
If your drilled hole is off center, I would tread lightly.
Or find another top half.
conomizer jet is deep in hole marked and some carbs did not have economizer jet.(quoted from post at 09:11:30 07/21/21)(quoted from post at 21:56:50 07/20/21)I am wishing you luck!(quoted from post at 20:28:41 07/20/21)(quoted from post at 18:58:40 07/20/21) The idle jet is 10-32 thread

It worked on another top that I have. Boiled it and the jet turned out easily. Now I would like to know where the economizer jet is located. I don't see any brass object in any of the other holes in the top casting.
Thank you.
(quoted from post at 09:11:16 07/21/21) He was saying he uses hot water before the jet is stripped... doesn't do any good on the one you already started drilling...
Jets are removed to inspect/clean/replace them and to clean the rest of the carb

Now I have a brass sleeve stuck in the threads. I am afraid to go to a 5/32" drill, but maybe that is what I need to try next. Thanks for your reply.
Sorry to be late getting back to you, but it looks like JMOR answered your question!(quoted from post at 09:11:30 07/21/21)(quoted from post at 21:56:50 07/20/21)I am wishing you luck!(quoted from post at 20:28:41 07/20/21)(quoted from post at 18:58:40 07/20/21) The idle jet is 10-32 thread

(quoted from post at 20:50:30 07/24/21) Hollow ground gunsmithing screwdrivers work well for me.
Pick your brand, but they may give you sticker shock.
Note the sizes on the handles. 3 and 16 work for me in most cases.
