Basket case bike carb question..?!?

[markjs]

I got my basket case bike's cabs out to re-assemble and as it turns out they have been out so long the diaphragms have shrunk up and it's gonna be hell hard to get back in right without a trick that I don't know. My guess is to soak them in some gas to expand and make them stretchy but I ain't doin' nothin' without one of you sayin' 'yeah, that's how I do it'!

I would soak them in brake fluid.

I agree with Scorpio1963, I soak o-rings in brake fluid to swell and expand them.
It might do the trick.

If they have shrunk to much they won't work proper in the carb, also could start to rotate on the slide and cause a vacuum leak.

you could order the new ones while you wait to see if the old ones go back to being a perfect seal. Then you could put the new ones in.
