I agree with what you say on this. I know it won't help because I was already there but, a guy told me to take it back 3 degrees and see and then move it accordingly. I think I am gioing to leave it at 37 and try 38. All I want to create here is just a consistant running car and now I think I am pretty close with just the carb adjustments. When I did bump it to 37 I felt it really woke up. I will try and find that article you mentioned.

Tuning For Power
Tune for power-makes sense, right? Many engine tuners don't look at it that way. They have a misconception of using benchmark numbers, such as brake-specific fuel consumption and air/fuel ratio, to guide their adjustments. For example, if you were to decide that a 13:1 air/fuel (A/F) ratio was the optimum number for your engine, you would change jetting to achieve it, and then leave it at that. Engines don't create the most peak power or best curves at a predetermined A/F ratio. The A/F ratio is merely a number you should take into consideration when tuning to keep out of the danger zone. At the end of the day, you are looking for the best performance, not a specific reading on the A/F meter.
The first step is to add fuel until power starts to level out. Once it does, then perform what is called a timing sweep. To do this, pull two degrees of timing out to see if there is a change in power. If there is no change, add four degrees from there to see if more power is gained with the more advanced timing. If the motor likes the increase in timing, keep adding timing until there is no change, or until the motor approaches an unsafe level of ignition timing. Once the optimal total ignition timing setting is found, remove fuel by means of a jet change up to a point to a loss in power. On most engines, this is the path to finding the most power. This is what I found so far. great info.
