A tornado. Huh.
OK, there has to be something wrong on your primary side. Without removing the carb from the car, if you can, I know you have a Turkey Pan, so do I, and hopefully yours is removable like mine, take the primary bowl off, look at the metering block, blow everything out again, make sure you have the gasket on in the correct direction (I kind of think you
can't put them on wrong anymore) and put the
old power valve back in. Then double check that, with the car not running, and the site plugs out of the bowls, that the electric fuel pump has the fuel level staying at just below the site hole and the needle and seat valves are shutting off the fuel flow and it's holding there.
