All helped, but in the end it was a cracked reed valve that caused the problem. Bought the motor on auction for a steal, was shipped from FL and the lowest intake reed block was starting to rust (probably salt water left in shipment horizontally), also where the cracked reed plate was. I replaced with Chris Carson reeds and stuffers and she runs 150X better...
One trick you can try is with the breather off, use your hand to cover the face of each carb one at a time, slightly rev up the motor, then take your hand off. Three things you should notice: Significant suction, residual fuel on your hand and often, if there is some blockage in the high speed jets, it can free this up. This can be repeated several times if necessary, just try to get a good seal on the carbs. In addition, with the breather off, it's worth spraying some carb cleaner while she's running.... If you get to the point nothing else is working, taking the carbs off gets a view into the intake and the reeds (with a flashlight). Best of luck man.
