Question Help with Clutch Return Spring

My 1986 325 needed a new clutch master cylinder. I managed to get it replaced but now as I try to reconnect the pedal to it it looks like I am going to have a problem. The spring at the top of the pedal assembly is there, and looks OK, but when I put it in it's resting spot and press the pedal it goes "over center" and by the time the pedal gets to the floor the spring is helping to hold the pedal down. It works this way even if I have the master cylinder rod hooked to it. It didn't do this before, so I am trying to figure out what I have done wrong on re-assembly.

Without the MC connected to the pedal the pedal sits way up high due to the spring pressure but, like I said, when I push the pedal down it gets to a point where the spring starts helping to hold it down and it will not return from sitting on the floor.

I have not touched the adjustment that appears to be in the spring bolt, and the location where I am mounting the other end of the spring is what appears to be a notch in the metal, holding the spring in a horizontal position. I have tried repositioning the spring, up higher, and probably not where it's supposed to be, but that actually helps a little bit, but does not keep it from going over center when pressed down.

There is nothing in the MC as I have not replaced the slave cylinder yet. That is next.

Can anyone tell me what I did wrong, and how to fix it?

Thanks,
Chris

OK, I'm trying here, but it is difficult to get a good pic and see what's going on because it's tight and hard to get a good angle.
At least one shows the pedal all the way on the floor.

I can try to get other angles if you tell me what you need.

Thanks,
Chris

OK, I found where the over-center clutch assist spring is mentioned in the bmw_e30_repair_manual_v7.pdf (page 365) in the sticky in the forum. It doesn't say much except that it is an over-center spring and needs to be in the notch, which I did. I guess what keeps it from staying on the floor is the push of the fluid from the clutch springs.

Well installed as per the manual, it it appears that the pressure from the clutch keeps pushes it enough to tip it back over the center, and it works just fine now.
What damper are you speaking of?
Thanks for the help.

Chris
