Hi Aaron
Have you cleaned out and checked the carburettor while you were changing the primer plate? If you have that's good, just check that its assembled properly. There is a idle screw on the air filter housing below your throttle control, undo the screw and it should be able to slide up and down thus adjusting the idle, this in turn should assist in giving you more revs.
The two wires you are talking about are for the kill switch set up.
