when you pull it over with kill switch off you should have the throttle pinned. What it does is keeps the pump from building pressure and keeps the injectors from working - so no fuel can keep coming into the motor, then you pull it over with the throttle wide open and it lets more air in to dry the plugs and forces gas into the exhaust.
So with the kill switch in the not run position, pull it over three times with throttle pinned as hard as possible. then turn the kill switch to run pin the throttle and pull hard a few times, it will ussually do the trick if it doesn't try it again.
The vise grips on the fuel line does the same thing.
I wonder if his fuel had water in it and froze the injectors open a little or something.
