Strange TXV setup

[Gary]

Except if his Madness is right (usually is) the #4 is too big and works only with migration so if the bulb is allowed to regain control it might not be able to turn down enough.

So put in a smaller orifice and wont wont work properly till the bulb eventually gains control if it ever does.

Not sure I like that scheme of things

Once the bulb is in control... if the TXV hunts, the orifice is oversized.
