Yes I have 12v's to the solenoid, coming from an oil pressure sender fed off one of a remote filter flange. I am thinking the issue might not be with the vaporizer or shut off..

I pulled the intake tube off of the mixer/carb to see if it would run off of carb cleaner or starting fluid.... and a bunch of coolant came running out. I don't think that seems right and probably has something to do with my coolant fowled plugs.

Thanks so much for all your input so far.
