Mix up the oil. put that side up, fill up to the shoulder. Let it soak. No way risking needing to drill is worth it. Patience.. A screwdriver, in the slot, and a few light quick taps every so often, shake it up, Not pounding it, it's brass and fine threads, not even a hammer, a small driver and an end wrench.. 9/16ths ish. Don't get harsh, induce vibration, while the penetrating oil is in it. Sometimes turning a stuck screw both ways helps. A bit of heat, doesn't require a torch, a soldering iron, even a blow dryer, anything to get those dissimilar metals to shift relative to one another. A squirt bottle with water to cool it, quickly, can cause crud to be crushed and release. Heat and cool may be needed more than one time. The time spent Not needing to drill is well worth it. A proper fit in the screw is crucial. Just because a screwdriver goes in doesn't make it a good fit. Does it go to the bottom of the slot? You've got a screw. Get the one from the other carb. Put the screwdriver in, hold it up to the light and see how well it fits. If it's tapered, it wants to Cam out. Shape the tip to do the job. Any brass displaced by the slippage of the screwdriver can gently be put back in place using a pin punch and a very careful eye and hand. I'm speaking from experience, not just pulling stuff out of my hat.
Lowe's sell a butane power soldering pencil for about ten bucks. Removing the soldering tip exposes a small but intense , blue, pointed, flame. Remember, that's aluminium. Heat is like Brylcream. A little dab'l do ya,, And, you'll have a portable, no cord required, soldering tool.
