Quick CIS question
 

I'm a rookie with CIS and just need a little clarification.

Am I right in thinking that the mixture adjustment only adjusts the mixture in the warm up phase, and when the engine is warm or higher than idle the O2 sensor and the Lambda take care of all mixture adjustments?

The 3 mm allen screw in the fuel distributor adjusts mixture across the board.

O2 and cat will attempt to adjust but can only do so within a limited range.

Warmup mixture is controlled by the warmup regulator (WUR).

O.k. I see, that's why you make sure to have a warm engine to adjust the mix. Thanks!
