au2 culster problem (with needles)

[Duffman]

Hay we took out the cluster to install white dails. Anyway all of the needles came off easy except the fuel one. It took the pin with it. Now when we put it back in it wont drop slowly like the temp guage it jerks or stops. We have tried putting it back in with the pin and cant get it to work right and now we are taking the pin out and putting it in on its own then adding the needle. Still it won work properly. Have we damaged anything or is it just a matter of messing with it until we get it right? Just it seems to run smooth for a bit then go jerky so annoying....
