Minimum & maximum recommended sizes for 4K (& 5K in some cases)
From my research
Choke:28, 32
Main:120, 200
Air:170, 200
Emul:.1,.6
Idle:40,58
Pump:33, 40
Generally the recommended worked 4K starting point is around: 120 main, 180 air, 35 pump, 50 idle
And interestingly TRD spec:
Main:160-200
Air:180-220
Emul:7772.2
Idle:50
Pump:33
My current spec
DHLA G
32 choke
