 Re : my 69 winter beater. I took it for a test ride yesterday  (95 degrees) and before I had gone 1 mile on local roads, I got a very heavy pre ignition knock not a ping. I checked the timing, it was right on target so I reduced it a couple of degrees. Some evidence of mouse activities are in engine compartment.
