Well, I'm learning, Allan and others are right.
These carbs need the angle or wedge plates under hard acceleration. What convinced me was the bowl and float arrangement of the 50+ year old WCFB's after I re-looked at the bowl/float arrangement after re-lifting the carb top. I guess you have to see it to believe/understand it. That front bowl is going to shut down the fuel flow under hard accelleration then when things slow down during the acceleration run (high gear in my case) the front float then starts accepting fuel then all returns to normal and she runs like he%^. I kept wanting to enrichen the rear jets but at this stage wedge plates need to be installed before anything else.

I really want to thank the responders helping me on this old school carb science project. Thanks guys! I'll report an update upon further progress.
