I had to drill out a couple. I ended up using a left hand drill bit. Don't use easi-outs. I had to replace one with a small nut and bolt.
A cheap kit like this did the job fine,

Before you try this leave the carb/s soaking in some diesel fuel for a day or so and then if you can get some Mole/Vise grips on the screws see if you can turn them out.
Also I always keep one of these around for focused heat and useful for several jobs,
