300/440/550 BN44 Exploded view

[Mort]

Anyone have a good exploded view of the BN44?

Im trying to figure something out, maybe someone knows. I took my bn44 apart the other night to clean it (the ski is new to me) and in one section of the fuel pump there is two of the clear gaskets "diaphragm's" next to each other. One is just a "ring" like a big "O" and the other is solid. didnt look right to me.

So i wanted to look at a reference.

Those two clear plastic gaskets do go side by side. I never understood why either. But all the BN44 carbs I experimented with on my 550 were built like that and the one rebuild kit I got a while back had a diagram showing them like that too.
