Tuning Order
If it's running, timing first. All settings should be done with the engine at operating temps.
Set initial timing to a number the engine wants. Not what some book say it was timed to from the factory. Stock 318's get 10-14 initial as an example. Bigger camshafts need more initial timing. Get the carb base idle settings squared away. Then move on to making sure your total number is not out of bounds and adjust as necessary.
The rest of it as far as carb tuning is next up. Jetting, power valve selection if holley, acc pumpsm, etc.
That's the way I do things
