Getting around to see what can be done about the lead
fouling sparkplugs causing the infamous "SAG". 1st experiment was
to place the used spark plugs in a 30% solution of Hydrogen Peroxide. I
did that and place the plugs and solution in an ultrasonic cleaner, turned it
on and left it on for 1 hour.
It appeared to clean everything off the plug - but, the
lead. So far the only chemical my research has indicated would dissolved
metallic lead is Nitric Acid. Nope, not going to try that, I'll stick
with buying new plugs.
But, thought I would let folks know of the
results. I was really hoping the ultrasonic vibration would shake the
lead crystals off the ceramic cone of the plug - but either the idea is flawed
or the small jewelry cleaning size ultrasonic generator is simply not powerful
enough.
