Either way it sounds like you have a major leak. Start by replacing all o rings.
In your climate I'd expect about 40psi low and 240 high.

Disagree.
Static pressure is an indicator of system status.
If you have 80 psi, and you still have 80 psi a week later, that's a sign the system is intact.
Again, depending upon ambient conditions, 80 psi could be a bit low for a static pressure, but you're close enough to get the system to engage.
I getting the impression the OP doesn't have a manifold gage set, since the only info we have is for the low side. We really need to know the high side pressure to tell what is going on.
If the low side pressure is going to 0 when the compressor engages, that tells me that the system is still low on Freon.
The limited info begs me ask the following questions:
Was the system open for any length of time before the recharge?
Was the system evacuated and kept under vacuum for at least one hour before recharge?
Was the system able to hold the vacuum reading overnight?
