Flooding and knocking questions
 

Ok I have a 1982 rx-7, I have been trying to put the thing back together after someone else took it apart. My question is how do you stop a carburator from delivering fule? and How do you unflood a rotary? Also, what would cause knock on a rotary? If theres something in the archives tell me and call me a nub because I couldn't find anything thanks for your help.
