Um, I seem to be forgetting something. I've just moved so my manuals are stored, and I've just finished a bunch of work on my car (1971 911T) including installing oil-fed chain tensioners and set carbs and been trying to make the car keep running not matter how much it rains. But the other day I got it to the best it's ever ran for me (only had it a while and mostly up on blocks doing chain tensioners), despite constant rain on the dizzy! and now somehow I have an idle around 1200 to 1400 rpm...

It has Weber 40 IDA 3C carbs, and I've done the whole setup, but the stress of moving and packing away the books has a hole in my memory... How do I reduce the idle speed? The linkage is proper, the car has ran at 900 nice and steady the whole time I've had it, I set the float level, I adjusted the vacuum, I adjust for popping and backed out screws... and the idle lever screws are not pushing on the idle arms or plates or whatever they are called.

But what the heck? Now (after the rain is gone maybe?) the car idles at 1200 or so.

Like it was always running on 5 cylinders perhaps? Like a wet wire finally dried out?

Oh, and NO popping spitting or backfiring now, no hesitation or stumbling anymore (and I thought it was just my tuning), but after taking the best two round trips of it's life with me (just 50 miles each or so). Boom, I've got high idle. And there is nothing that I can remember to turn down.

The black knob/lever between the seats is not pulled on by mistake, the idle screws are not pushing the plates which would push the linkage, I can't think of a thing that is causing this.

And now I can't remember, okay, so if everything was fine and I wanted to reduce the idle speed anyway... like say to 600 for some reason... why can't I remember what would do that??????
