Easy job...
Change the idle jet on an LX..
4 screws off, tinker, tinker, 4 screws on..
A reminder which has been stated before,( I know I read it before I started the job), the bowl screws are made of the worlds softest metal.
Use the right size screwdriver and maintain pressure when you try to remove them.
Now I have to find some new ones....

Good news is that I installed the new jet.

Is it normal for the idle jet to have a smokey smell to it?
My jet has a very deep smokey aroma, so smokey you can't even smell gas.

Just a question and some carb advice to the unsuspecting.
Thank you.

The problem is that the screws are JIS head, which is not quite the same as US Phillips heads. Phillips drivers strip JIS heads easily.

Solve the problem permanently by using flat head replacements with an Allen (hex) drive.

Yep
Finally, after a half-century of stripping out allen heads, I bought a set of JIS-style screwdrivers a couple of years ago. If I was still limber enough, I'd kick myself.

What's the saying about too soon old and too late smart?

Surprising, the number of gadgets with metric screws and JIS-style heads.

I don't believe I've had to buy a replacement screw since I got the right drivers. Cuts way down on the cussing, too.

The OP is probably lucky it stripped out the heads before it stripped out the threads on the carb body. If the scews are made of the world's softest metal, the carb body runs a close second.
