Change size of hamburger icon in Fulton

I've been trying to change the size of the hamburger icon using the Fulton template but have not been able to figure it out. Using the code below changes the size of the label that can be clicked but not the icon itself. font-size seems to not make any changes either. I'm not sure if the actual icon element has a different name or where I'm going wrong. Any help would be appreciated. 

.mobile-nav-toggle-label.show-on-scroll-mobile {
  width: 200px;
}

.mobile-nav-toggle-label * {
    width: 50px !important;
    height: 3px !Important;
}
