OK, here’s an interesting observation / dilemma.
I have a strut brace-bar in my engine bay, the typical round, chrome bar as sold by MSA. (attached pic)
When adjusting the idle on my front carb, the screwdriver shank contacts the strut bar, making a metal-to-metal contact.
When adjusting my idle speed the other day, I noticed a weak “ignition spark†from my screwdriver tip to the idle screw, just before it touches.
So it looks like I have a high voltage leak somewhere in the ignition system, but can’t find it.
At first I thought the ignition wires were to blame, but it happens with both my old and new ignition wire sets. I’ve verified that the high voltage ignition wires are not contacting metal anywhere, and are at least 1/4†from any grounded metal surface. Same for the high voltage wire from the coil to distributor.
Further, I can grab any of the ignition wires without feeling a jolt. - (Dumb mech engr type of test). After all, if I can’t see the electrons, they don’t exist and can't hurt me, right?
Any thoughts on what to look at next?
