246 distributor Cetrufugal weights

I don't know if this picture helps you....This is from when I disassembled my original ignition system.

The weight is shown left in Peters picture, to the right are the two pins with a shim and spring each. You should have the parts in Peters picture 2x, each weight has two pins/shims/springs. Ususally there are also very thin washers between the pin and the shims added when setting up the distributor curve.

If one of the pin/shims is missing a spring then someone messed with the advance mechanism. My recommendation would be to have a competent workshop with a distributor tester checking out the advance curve and recurve the distributor if required (very likely if parts are missing).

P.s. it's very important not to mix up the pins/springs/washers/weights when you disassemble the advance mechanism as this will change the advance curve.

 

Ok, please be aware that an advance rebuild kit is never plug&play, you need to have access to a distributor testing machine to do the recurving, and usually also additional springs and washers.
