Seadoo 787 carb rebuild problem! Need advice

[yz450fpilot]

I was reinstalling the screw for the seat clamp on my carb when it started to feel soft. I thought I had somehow stripped the threads, but the screw actually broke off halfway down in the threads. How would you attack this tiny problem? I don't have a screw extractor this small.

It is going to be really hard to drill without getting into the soft aluminum.
Your best bet will be a small pick and try and back it out. Make sure to use some lube to help.
