Hi Joachim,
Since no oxygen sensors were in general use when the JH was built tuning was done using Co readings. The manual states 1.2 - 2% Co at idle for the 4 speed and .2 - .3 % for the 5 speed as emissions were further regulated, (sounds kind of lean).

Judson has used exhaust gas temperature readings to tune Dellortos.

I prefer the seat of the pants method.
