thanks CY and Zyp for being persistent about undercharging.
what i learned:
1. not to rely solely on hi & lo pressure readings. while the hi & lo
pressures looked acceptable, i should have paid more attention
to evap inlet & outlet temps.
2. not to rely on the sticker in the refrigerator which stated 4.000
ounces of R134a. summary, the total charge took 275 grams
(nearly 9.7 ounces) of R134a.
IT'S WORKING PROPERLY NOW!!!

Although you believe the liquid drier is that same, it may have different
internal space than the OEM. No matter how you cut it, there's a required
amount of liquid still needed from the metering device to the condenser.
The liquid drier is part of that circuit.

'Liquid drier' is such a wonderful term ... :-)

In the factory, the charge is fine tuned. The
initial charge may be installed but the tech
will tweak it. Heck, a repair should use the
factory spec as a starting point. Darn finicky
little refrigeration units. I like the big ones
with a sight glass, receiver tank and a TXV
on the evaporator. *snicker*
