Default SAITO FG 57 carburator

Hello,
6 months ago, I dismantled the carburetor of my FG-57 for changing the diaphragms. For a lot of reasons, I dont change it since today!
My problem is that with my dismantled parts, I have a spring (see picture below) and I don't remember at what place it have to be!

Thnk's for help.

Hello,
The spring is located under the pump diaphragm, those WALBRO WYD carburetor have a pump who work only with negative pressure generated into the intake manifold

Hello, this week-end I take time for trying starting my FG57. One month ago, I reassemble my carburator, with new membranes, after one year disassemble. Ik looked the marks on the membranes to remember this mounting order.
After longs trying the engine started, at low rpm, but don't react when I change gaz position. I put the engine out of the pane and mount it on a test support, after verifing that the bushel moove right.
I anybody could give me the mounting order for all the membranes?

Thanks.

Pierre.
