Thanks for the reply, I've heard of using pieces of vacuum hose. I've
also heard of using a piece of coaxe-cable, like you use on your tv.
Ground one end to the engine block, strip the insulation back off the
other end far enough so you can backprobe the plug boot and short the
spark to that cylinder.

When I was using the screwdriver, I was trying to see if the spark
would jump to engine ground. The insulation on the handle may have been
cracked or the handle was greasy, maybe, don't know. thanks
