'78 Kz1000, had to drill out stuck pilot air screw

However I did not drill it to the maximum diameter of the threaded hole in the carb to protect the threads. Now I've got a thin layer of whatever the original pilot air screw was made of (brass probably) and I can't get it out of the threads. Also, there is of course a spring down at the bottom of the hole that the pilot air screw goes into, and that's still down there.
Any suggestions? This tiny sucker is kicking my azz.

My best friend is an industrial engineer; he told me about this stuff because they use it where he works. I ordered mine from the maker (Kano Labs - see 1st link). I bought one "Kroil 1/2 pint (8 oz.) can - $9.25 ea." from their order page (see about halfway down the page in 2nd link) and have been using it for about 8 years. A little goes a long way. I have not tried the AeroKroil, but frankly I wouldn't buy it in the aerosol form. The regular 1/2 pint can I bought has a built in spout that works well.
I have also seen it for sale at gun shows.
The first time I used it was on the threads on the rear master cylinder brake rod that I had first tried very hard to turn with no success. I soaked it for 2 days. After the soaking it turned so easily I thought something was wrong. Happy camper! I have used it on the original screws that fasten the carb holders and the tach drive screw to the cylinder head and they came out very easily. None of these fasteners had ever been touched in 27 years.

But I cannot tell if the thread pitch is 1.25 or 1.50.
I have to re-tap the pilot air screw hole in the #2 carb, and (of course) buy a new pilot air screw so I need to use the right tap.
Is the pilot air screw 8mm x 1.50
or is it 8mm x 1.25?
HALP.

wireman, 1.5 thread pitch, 8mm x 1.5 is what I'm thinking too, fine threads on these idle screws, and I'm screwed too because the local hardware store does not sell 8mm x 1.5 thread pitch taps, dang it.
