I have an Aerocarb/Aeroinjector on my 2200 (2012 hydraulic lifter), which gives manual mixture control.
Instrumentation is a Dynon 180 with 4 x EGT/CHT and fuel flow.
I find the fuel distribution on mine at 2850/2900 RPM tends to run rich on 3 and 4, leaner on 1 and 2. Number 1 is the leanest.
Maybe because of the longer intake tubes.. I dunno.
#3 CHT is always the hottest. I should take some air from #2 and duct it across the engine to #3.
I manage fuel flows using the mixture control, I expect to see 25Ltrs per hour on takeoff and EGTs below 700. If they creep over I tend to back the throttle off slightly.
Cruise I will lean to around 15-16 litres per hour, any more and it will start to give little burps. EGTs #1 will be around 700-710C, #2 will be around 680C, 3 and 4 around 640C
The early aerocarbs are a little rough with their manufacturing tolerances and RPM/mixture tends to wander a bit.
This is a shot of my panel cruising at 3500' to Ehuca last Saturday. Fairly typical numbers, I think OAT was around 12C.
