Thanks for the ideas but now it is too late. After a few hours of soaking with penetrating oil I tried it. There was slight movement in both directions with the 5/8 open end wrench. After doing that for a while I guess metal fatigue set in and it suddenly got easy turning. I have a new project for tomorrow now. If I remember right we had to do the same thing on the original carb on the 52. I knew a guy that could fabricate a new bolt with the right thread luckily and we got that one working. Hardest part now will be to drill out the stump without damaging the carb threads.
