ok i got the linkages figured out and the diaphragm worked once i got everything else connected right. i put the carb on and it ran great but im curious doesn't the diaphragm pull up and open the secondary valve all the way under full throttle, cause the only time i see the secondary valve move is the little bit it opens by the linkages do you have to be going down the road for this to happen or should both barrels open all the way by the truck sitting still and mashing the pedal all the way?

 

i drove the truck today and it felt like it had no power and could barely get up to speed it bogs down if u try to accelerate hard i dont think the secondary barrell is opening while driving . but it runs good and accelerates fine while sitting still and i kno the secondary valve isnt opening while reving it sitting still somebody please give me some advice or explain what they think is happening this is the only thing holdn me up for drivin

 

Do you have the secondary diaphram hooked up to the correct vacume port?

And in the future, please keep all this in one thread.

 

there is no vacuum lines on my diaphragm

 

Post a pic of your carb without the air cleaner from the drivers side and post it up.
