My 94 xj is having trouble starting every once in a while i traced it to my NSS, i planned on removing it and cleaning first since a new one is fairly exspencive. I removed the mounting bolt and removed the large nut but i am having a tough time getting the assembly off. I am a little nervous using to much force because i can't afford a new one if i break it. any of you have suggestions or tips to get it off thanks
