The last time I had a toilet with a chain which occasionally "kinked"
and wouldn't let the flapper down I replaced the chain with a piece of
nylon fishing line and "Bob's your uncle".

Dottie,

Nestork's advice is good. Also, often the excess chain can get sucked
between the flapper and it's seat. Be sure that the excess chain can not
do this.
