I had diaphragm on my carbs that had some little bubles in it (not pearced). And I was wondering what would be the trouble if this diaphragm would not create the proper vacuum? It's an inline four.

No vacuum doesn't suck.

Except sometimes, when it does. Like when your carbs don't operate properly. And that is what happens when the diaphrams on the slides have holes in them.

With no vacuum you would get no fuel to your carbs ,the vacuum opens the fuel tap

True, if it's the petcock diaphram with a hole in it. If it's the diaphram on the slide in the carb, then the slides don't see the correct vacuum signal and react accordingly.

Either way, a diaphram is a diaphram and should not have holes in the membrane......

Could this lead to a sudden loss of power at high RPM range (only in charge)?
