mast twists half inch and main halyard gets super tough to raise last six inches

Just bought a 40 year old FS. My first one and two things I noticed.
Mast can twist by hand half inch either direction and its in a sleeve? Is that bad. what is the cause and how do I fix it
Main is very hard to raise the last 6 inches. So tight i leave it three inches short from the top. Haylard not twisted. Lots of tension the last 6 inches. Why and how to fix
Thanks for any suggestions
