Idle Mixture
 

Brian,

When you say idle mixture... are you referring to the DWUR or is there another adjustment on all cars for that?

I realize their is a basic mixture next to the fuel distributor with an allen wrench but if someone were to adjust, the O2 sensor should auto adjust it back to compensate... correct? Just wanted to know what you were referring to and if normal (old style WUR) cars could change that mixture curve at all.

Someone said I could lightly tap on the fuel distributor where Leask makes it adjustable but I was never sure what that would do and if it went to far then I have to take it apart.

Thanks,
Bryan

Yes I was referring to the idle fuel mixture adjustment located on the air meter assembly by the fuel head. No Lambda controls as those are disabled and CO adjusted to 3%. That CO level will change of course as you move toward 14:1 AFR at idle. Good place to start.
I have not kept up with the Digi-WUR thread so don't know exactly how this version works. I think it is safe to assume that idle mixture is still controlled by the fuel head which would set the baseline for the entire fuel curve. This needs to be confirmed by the dig-WUR folks of course.

cool..... so I'm not the only one who gets grease on their pajamas
