Take off the covers & you'll see where the diaphram has pulled away from the perimeter (highly likely) so it's not sealing & therefore leaking there or the diaphram has a split somewhere & you'll see it if you take it out of the housing. EDIT Do Buildanothers' test first

my outboard carbs on my sixpack are not working i checked vacuum to the carbs and it does have vacuum so with the engine not running i opened the throttle on the center carb and i sucked on the vacuum hose to the outboards and the back carb moved very little the front one did not move at all so i ordered new diaphrams i hope that fixes it plus when i was sucking on the vacuum hose i could hear the air flowing through the diaphrams like they were leaking anybody have any input it would be greatly appreciated thanks.
First thing I see wrong is you have the vacuum line connected to the distributor vacuum port on the center carb metering block instead of to the main body.

I appreciate that i guess the base plate will pull more vacuum thanks.

It doesn't go to the base plate,there is another port behind and lower on the main body,the tube may be missing.

While you have the pods off, make sure that the kill bleeds from the pods into the carb throats are clear and that the cork seals are in good condition. I usually change the seals if they are very old at all.

I'm thinking no it isn't.... looks like it's not plugged onto the proper tube. The port on the metering block is for the vacuum advance hose and that appears (at least in the pic) to where you have the hose plugged onto. The proper port is on the main carb body about 3/4" behind and below that. 
Pardon me if I'm wrong when looking at your picture, but if it is in the wrong spot, hooking it up correctly should be an eye-opener when you mash the peddle!!!!

okay thanks i appreciate it.
And once you do that and if you don't connect the vacuum advance,cap that port.

He's right, the engine has to be under load for the secondaries to open.
Did you hold the stems up so that the edges of the diaphrams are as far out to the edge of the pods as possible when you screwed the covers down?
And which springs are in the pods? They could be so stiff as to completely keep the secondaries from opening, depending on your engine.
Are the little cork seals for the kill bleeds in good shape?
That's all I can think of right now. Good luck!
Master, again and still
