Grounding issue ?

[Mitchel Seff <ms6453@optonline.net>]

Hi all,

I'm experiencing an unusual problem & need some help. I have a 
inconsistent stutter at low rpm's ( 800-1,500) under light load when 
leaving a light. It's not there all the time but with enough frequency 
to be annoying.
I have check & changed points, cap, rotor & timing. I am running an MSD 
6A. I by passed the MSD and the symptoms still continued. It definitely 
feels ignition related. All other driving conditions are normal. One 
thing I did notice is a slight arc when I hold a screwdriver to the 
head. This has me stumped. Any help would be appreciated.
