I am trying to replace the 2 sensors....the rear one, believe speed sensor is stuck. I can get it to twist back and forth about 20 degrees but it just won't come out at all. I sprayed some penetrant to wet the O ring and it twists easier but as much as i try it will not come. Is there a trick to this?

 

Well, I got it. After 4+ hours and manycustom made tools!! There was some grime on the end of it when it came out. One thing i noticed was the new one is magnetic and the old one wasn't. Anyone know why? Still dosen't start by the way. It seems like it wants to nowbut it won't fire.
