The recommended idle speed increased over the years - from 500 up to 900 and
possibly higher - as the spec changed and emissions crept in. My UK 73
roadster needs all of its 700-800, for example. With that much trouble, I
would suspect a problem or something isn't to original spec.
There are curves for most applications on my web site - select 'Spanners'
and 'Curves'.

Subject: Idle speed and timing
The Haynes manual says that for my 1967 B the timing should be set to 14
degrees advanced at 600 RPM with the vacuum advance disconnected.
Does anybody else have a problem getting their car to even keep running at
that low an idle speed? I need my B to idle at least 1000 RPM to get any
sort of smooth running out of the engine, and really 1500 is better.
Can somebody please give me a guideline on the proper advance for timing at
a higher RPM ¯ or does the idle speed even matter?
Thanks, as always I appreciate the time the experienced listers take to
educate the rest of us.
