Clone recoil starter: missing part?

[Ken]

I replaced the rope and rewound the spring. Now that it's reassembled, the pins won't come out and engage the starter cup. Checking online I believe I'm missing a "friction spring" behind the cover plate. This photo shows the back of the plate with the shaft of the bolt where I believe the spring goes. Is this part available anywhere or might there be a generic spring that will fit?

you might be able to get one at a lawnmower shop or tool rental place.... they both maintain stuff like this so having a spring like that is possible...
