    That's the anti reversal latch it goes on the bottom left near where the more enters the gearbox

    That's the Anti-Reversal Latch spring.

    It goes on the ARL to keep it pressed against the bevel gear.

    the lever needs to be pulled down when installing the bevel gear. the spring pushes the lever against the notches on the bevel gear to prevent the gears from rotating backwards after a complete cycle.

    That's pretty normal, actually.
    Try a drop of silicon grease to help hold it in place.
    Some people also use rare earth magnets on the outside of the shell to hols them.

    Higher end gearboxes have tighter tolerances, so it's easier on those.

    That is a very common issue with AR latches. You can try placing a magnet under the GB shel while closing the gearbox, or put a blob of grease in the hole for the AR latch.

    if you have a neodymium motor, use that under the gearbox.

    place the motor underneath the gearbox where the cutoff lever is located. the magnet from the motor will pull the cutoff lever towards the gearbox shell so it doesn't pop out when closing the gearbox halves.

    keep your post on the open forum so everyone can benefit. i don't do public tech support on PM.
    start a new thread on your spring issue and be specific.

    If you bend a few MM of the tip of the ARL spring, it will be much easier and work just as well.

    Be careful though! I tried to do that and ended up snapping the spring

    If you're careful about it you should be fine. I would recommend a pair of pliers, though.
