Your pump timing is too far retarded by those symptoms.Try to get it 23deg before tdc and see what happens.Are your timing marks right?
Good luck
Also temporarily disconnect the fuel line to that thermostart to be sure it is not leaking fuel into the intake manifold.
Any possibility of oil coming in through the turbo?
Well the prize goes to Enginenut My son(and I๐ฎ ) somehow tyed the return fuel line into thermostart circut above the valve unit ๐ It the simple things๐
