hi donny great news you have you mower back in action again
if your shure throttle cable has some slack and engine idle is till to high next step is to remove aircleaner, for under the aircleaner assembly you will see throttle linkages governer spring ect
look for the throttle arm lever this lever will have a idle speed screw that controls idle speed when you move throttle lever to slow position
try backing the idle screw out a bit to see if that slows it down a bit
