fuel mixture screw head stripped and seized

Can't get it out. Any ideas?

Use a small pick, such as a dental pick, to clean out the slot in the screw. Then use a metric sized slot screwdriver to remove the screw. Applying a penetrating oil and letting it soak for an hour or more should help. ATF and acetone mixed 1:1 works well.

PB blaster works good, apply generously, let rest 24hrs, reapply
Heat helps also.
