Fuel pressure and ignition timing checked out-concentrate on the transmission-could be a problem with the vacuum modulator-

Lets narrow it down, does it feel like a shifting problem, or a fuel problem? Does tranny wind up and not shift? Or is it fuel starved? The floats may need adjustment...

it does wait to shift more than what i would think it should and it shifts hard but goes through all the gears...i did what the carb instructions said for the fuel and air mix but that doesnt guarentee its right!?

And your detent cable from the carb to tranny? Is that set up so it kicks down when you stomp on the gas? This could be a part of the shift problem. If not set up right you will have low power on uphill climbing and getting on it when already moving, no downshift...If you belive the carb is set up right, and there is a lack of power, try getting another carb, yours could be defective. Your carb's gas pump is moving on acceleration?
