Want to discount my plug wires from being an issue...
They are stamped Brem 30/06 which I assume means the are Brem made and manu date is week 30/2006...

They look fine, and have done few miles, and the resistances come in @1.1 to 1.24 K Ohms.. the 1.24 is on plug wire for #2 cylinder.

Is that good?
