This is a pic of the part, number 4 5 on the left side, What does it do?

the plunger and spring are for the decompression mechanism on the stock cam. if you have an aftermarket one, you will not be using either part. with the hotcam you are running it is not needed so you are good to go there. just make sure there is nothing in there before you put it together. steve
