I agree, use a left hand bit , but you may want to do this on a Bridgeport Mill to get the drill exactly on center with the jet . If the jet doesn't bite and twist out , then drill it out and retap it , if you can't pick out what is left of the jets threads . leave the carb setup in the Mill so everything stays lined up . Use the chuck to align the tap . Left hand bit needs to be the size that would allow you to tap that thread size .

Mr Smith et al,

I have run across a lot of these type stuck jets from some over zealous dude overtightening the jet(s). Whenever I can't get the impact tool approach to work, I just drill the jet and use an appropriate sized (#2 or #3) ezy out tool. That method has always worked and I always run a tap through the threads afterwards. Of course it ruins the jet, but new jets are cheap compared to losing a carb casting through hammer and tong approaches.

Jets shouldn't be tightened to much more than about 40 inch-pounds anyway.

Hope that helps solve the problem for you. Good luck.
Regards,

Tried all the above suggestions to no avail.The jet next to it was tight also.Got it out with a little heat from a heat gun.Finally had to drill it out in steps.Im pretty sure it had been cross threaded in place at one time.Maybe even from the factory.Thanks for all the suggestions.
