What should the CO % be at 3-4000 RPM when I'm cruising along

[KernowCooper]

What type of mini do you have? Carb or injection? and is it modified like cam and head ?

 

My 1330 with a stage 4 head and a 276 cam and a Aldon Yellow on a HIF44 under those conditions is about 1%CO

 

1.0% CO or a 14.1:1 AFR  with a Standard / Mild performance engine; or 1.0% - 3.0% CO or a 14.1 – 13.4:1 AFR with high performance cam; 

 

Any less than 1% on Carb engines and you can find it very snatchy on a very light throttle   AFR by the way is Air Fuel Ratio which lots of Gauges report in with a Lamba Sensor, they respond quicker than a conventional CO machine.
