Thank You all for your assistance,
33Willys77, it is currently at 22 and I tried 24 this afternoon which is starting and idling fine.
F-BIRD'88, it is idling fine at 24 right now, so how high should I go? Do I keep going up by 2 degrees at a time until I cannot start it and then go down 2 degrees?
MouseFink, I have no idea what the compression is and I have no details to be able to calculate it so hence my question as to figuring this out using other means. The vaccum advance is disconnected and plugged so not a variable in this. Please clarify what you mean with your comment of 'If the engine idle speed cannot be turned down below 900 RPM you cannot set the initial advance'. Engine was running but barely holding in there at 700 rpm with 24 degrees so I turned idle up to 850 and it now runs fine (but it may be getting close, if not already, running on transition slot).
