[Healeys] black smoke

[Richard Kahn]

I must have mislead everyone. I only got the black smoke when I set the slow
idle at 2 1/2 turns during set-up. At 1/2 turn open there is no black smoke.
Colortune is blue. Plugs are light tan in color. I have lots of power and good
acceleration. I just cannot get the slow idle to 600.  I am just wondering
about the almost closed slow idle setting.
Thanks for all the interesting responses.
