Hi Ahmed 
Here in NZ we have some old Bruntons that had this problem, and someone twisted copper wire around one end of the needle to correct the weighting... its cumbersome but does seem to work.

Dear Colleagues
 
Actually I bought a new Brunton Compass and when i tried to use it in the filed here in South Africa, it seemed that the needle does not move freely!
Should I reverse the weight attached to south-seeking end of the needle? or what to do ?
 
Can anybody help me how to solve this problem!
 
Thanks
Cheers
Ahmed
