No. You gave a rambling account of what happens and what you see, without even mentioning what you are trying to fix (one assumes a lawn mower), nor the make nor the model.
You are not really helping much, are you?
You MAY, with a suitably diligent bit of searching, be able to find a parts diagram or even a maintenance manual, for either the mower or the engine it uses.
