Personally I do not like the word "stomp" thusly that may be part of the problem. Take notice of the location and position of the starter actuator then apply a firm and gentle pressure with the foot in a forward and downward direction. The actuator is mounted on the angled firewall portion while most people try to push straight down. Additionally, observe all pivot points for lubrication, there is one on drivers side top of bell housing and passenger side. I also place a small dap on grease at point of contact on starter.
