Either the regulator you got or the POL adapter is not flowing enough gas, it is that simple...
HOWEVER, 4" might still be enough pressure to run it since the next stage is reducing it to negative. I have seen them run with no tank connected, until the fuel in the pipe was sucked out, so....
If you can get your hands on a bigger regulator setup, it is worth a shot, but I think that if that is any trouble you should try turning in and out the load block screw first since it is easy to do. You could also try checking the pressure coming out of the Maxitrol regulator to be sure that it is slightly negative when the engine is running if you can get it to run
Another thought-if you can get it to run the previous way, measure the pressure at the inlet to the Maxitrol and see what it is at when it runs but be careful not to blow up your gauge if it cannot handle high pressure....
