If The Rotor Is Loose On The Shaft Will The Car Shut Off If You Rev It Up? The Car Will Idle But It You Try To Rev It Up It Shuts Off Like It Looses Spark Or Something. Does The Rotor Have To Be Tight On The Shaft For The Car To Run Properly? I Lost The Original Rotor Screw And Found Another But It Wouldnt Tighten All The Way
