I thought DPR amperage was the lower the richer
Nope. Other way around. More current = More fuel.

80 to 100 mA. I probably messed these up trying to nail that +-5mA.
Going to check these values again.
It's easy to check the cold-running enrichment and after start
enrichment.
Hook up your meter to read DPR current and unplug the connector from
the coolant temp sensor.
To check the cold-running enrichment, turn the key on. The DPR
current should be between 80
and 100 mA. To check after-start enrichment, leave the CTS
disconnected, and pull the coil wire
out of the center of the distributor cap and ground it. Now, turn on
the ignition and run the starter
for 2-3 seconds, then leave the ignition on. The DPR current should
jump to over 120 mA and
stay there for 30- 60 seconds, and then drop back to the 80-100 mA it
was at with just the ignition on.
Don't get too hung up on the 5 mA number for "normal" DPR current.
Depending on what, if any,
modifications have been done to the engine, and it's health in
general, it could run fine anywhere
from +1-2 mA to +10 or so mA. Mine likes it around +2-3 mA (engine
not stock). Remember that
when you're checking/setting the DPR current, that it's VERY
important that the engine be completely
warmed up, as in driven pretty hard for 7-10 miles depending on
ambient temperature.
