Howdy all, back new to the list here.  If that doesn't make since I was a
list member several years ago, and just rejoined 2 weeks ago.  Been lurking
since.

The above is true Randall, SUs vary at idle due to a variety of influences.
But that is a real problem if you live in a state such as California and if
your car requires annual or periodic emissions testing.  In the case of
California one of the test involves idle emissions testing and the idle must
be within a set max and min rpm.  This can be hard to get, you set them at
home, and all is good, then the smog shop runs the engine under different
conditions and the idle may, or may not, fall within the low speed idle
specs.  I have been fortunate and not yet burned by this, but it has been
close a few times...lol

Now that 1974 vehicles are emission testing exempt in CA though, I will not
be having this problem as much.

Darrell
1962 TR-4 (x3, one daily driver, one weekender, one project)
1967 Spitfire  beater, but driver
1974 Spitfire  driver
1977 Spitfire  daily driver  (mine)
1978 Spitfire  driver  (soon to be youngest daughters)
1979 Spitfire  daily driver  (wifes)
and several other Triumphs, all in bad shape...lol
