Makes sense - will try that per the AFP manual.
Just out of curiosity did you see any issue while at cruise power?

Above 6~7 GPH, flow division is function of nozzle restrictor size. At that point the piston in the flow divider is raised enough to uncover high volume ports, allowing fuel to bypass the metering slots. Those slots control division at low flow rates. As noted, the slot feeding #4 probably has some trash in it. So lean cylinder when at 3 GPH (slot blocked), normal at 19 GPH (blocked slot bypassed).
