Default Knocking noise?

Every time i start my 94 miata the engine knocks for about 2-3 sec. Its not loud but you can hear it real good.

You're giving no details as to what your car is. You have given no info on what you have done to the car. At this point, I'm gonna tell you to go to miata.net and look up HLA flush.
