just found this, great i was stuck, and my wafer was covered with grease and until i knew what to look for i could not see it. Now I have it apart, and ready to reassemble. How ever, should it just snap in place and hold lock in with a snap of the wafer, or do i need to depress it? Thanks, also any special grease or none? Clean it with WD40? Thanks again, can't wait to figure out my lack of ignition power, thought it was the switch but replacing and still not working. I'm on my way to diagnosing the problem.
