Thank you all for the suggestions.



Good news is the baby survived the operation!



I tried all of the above, soaking in carb cleaner, soaking in penetrating oil, (both over night), then heat, (did not dip in cold water as I was afraid of cracking carb.), then I tore up the head pretty good after all these attempts. Finally drilled, easy-outed, and then re-tapped.


Turned out very well. On to next step.


Thanks again
