Cow magnets are used by cattlemen to prevent injury to cattle from ingesting nails, staples, bits of barbed wire, etc. when grazing. The metal objects do not pass thru the cows digestive tract, but due to remaining in their system inhibit milk production. The magnet is 'fed' to the cow when fairly young, typically at branding, and resides for life in one of their four stomachs. They causing no discomfort, simply attracting the swallowed objects and keeping them from catching on the cows stomach linings and causing the low-grade infections that influences milk production.
When you live in Iowa you learn such things...

Green grass. Mike, "Theorizing, Visualizing, Practicing, Modeling, Pontificating, Opinionating , etc. You can play with semantics if you wish. If I spent my time indexing plugs, I too would say I felt or noticed a difference." Practicing, meaning actually trying things and observing the results, isn't an issue of semantics. It may be an issue of accurate observation versus self-delusion, yes. If I were having trouble with cold starts and plug wetting, especially on a vintage machine that I wanted to keep stock, what the hell, I'd try it and trust my own observations. If you don't want to, fine with me. >Ignition has nothing to due with plug wetting unless it doesn't fire. You've only made my point. Wet plugs _don't_ fire. That's the point. Turning the ground strap to shield to center electrode from the incoming "rain" of raw fuel seems to help keep them dry enough to fire on a cold start. Funny how one can learn a LOT more by reading papers written by REAL engineers and scientists--who, back in the 1930's, tested MANY piston engines to DESTRUCTION--because pilots' lives depended upon their research--than you can learn from computer simulations--ISN'T it ?? Back then, the experimenters didn't worry about what was 'politically correct', they worried,worked, and OBJECTIVELY analyzed what actually WORKED in the REAL world--not on a silicon chip !! And they strove, mightily, to avoid letting the NIH syndrome and personal agendas interfere with their interpretation of test results !! There's a potent lesson in the above !!
