Folks I am at a loss. My '72 1.7 with stock D-jet works almost perfect. But I can not get the engine to idle at higher RPM when I first start it.

So here is what I know.
When cold the engine starts on the first revolution and idles at 900 to 1000 rpm. Same after warm up.
I adjusted the Throttle Pos Switch today and exceleration at operating temp is much smoother and responsive (probably has nothing to do with the warm up idle).
I pulled the AAR today and it works as it should.
Checked (again) for vacum leaks and all seems OK.
I did pull the oil bath air cleaner off and replaced it with a paper filter from a '73. So the engine no longer has an intake air pre-heater.

So with that little bit of info does anyone have a suggestion?

I suggest driving it and not worrying. I think that's more than "close enough for government work"...

A lot of people wish their car acted just like yours.

But it is so close and I am so anal about little things not working. Not complaining just doin some head and chin scratching.

ignition timing can have a significant effect on idle speed; check that.
