Setting idle rpm?

Do you own or have access to a Dwell/tachometer and a Vacuum Gauge? Without these tools whatever you do is just a WAG. With these tools and the information found at this link -

I just noticed the heading of the article say without a timing light. Could I just use a timing light?

Gotcha. Thanks again.

Boy does that ever bring back memories .  I used to love to watch my Dad tune his (our) '47 CJ2A L-head with a vacuum gauge, timing light and his left ear.  The right ear wasn't so good as it was the ear he used while on the phone at work all day (   ).
When he finished, that little baby would purrrrrrrr and had smooth power everywhere!!!  Sure am glad he took the time to teach me how to work on the Jeep.  I never learned the ear thing quite as well as him, but I do ok.
