My guess would be leaking air at the base of the carb. If you can put your finger over the carb opening and it doesn't die try sealing the carb base.
I tried that, and it finally died, but it took it a while. I took the carb off and reseated it, but I don't think it solved the problem. When you say "sealing the carb base", what method do you use to seal it?
maybe a little RTV around the base of the carb would seal it. It seems I am remembering several people complaining about this same thing with this particular Magnum engine and I am not sure it was ever resolved. Some time back there was a long thread about. It was in this forum so maybe some that have owned the engine will join in.
