You have to consider the size of the idle air bleeds and the main bleeds.
What you guys are getting into is as complicated as jetting Webers but you can only increase the size of the air bleeds (air jets) since they are pressed into the carb housing.
I am with you there. which is why you really can't compare the jets of todays after market carbs to the listed jetting 30+ years ago. Most carbs off the shelf typically start on the rich side anyway which is safer for the manufacturers and the users.
I would love to see, compare, and discuss what different people are doing and how they are changing it. Most carb discusions talk mostly of just jets and power valves. There is so much more to them. It may be more then many people would like to get into but I enjoy it. We have been making some changes to some carbs we have been working on adjusting everything from the bleeds to the emulsions and we have been succesfull at getting the these things to run like they are fuel injected. We are not always 100% confident in what we are doing but that is the learning process and that is the fun!
Non of this would have been remotly possible without an LM-1. When working with trasitions for examle, we can accelerate moderatly and see for example "wow, fuel/air went to 9, now it's catching back up". You question what is going on as you are driving it. You look at a fuel to air ratio meter and there are no questions. You see exaclty when it goes rich, under how much load, watch the rpm, etc. You can see things happening even before you hear the effects.
