[AJD] Champion Plugs - was Re: JD 70 running rough

[John]

  One hears a lot of antecdotal evidence of Champion Plug bashing lol of 
which I may be guilty as Ive also had better luck with Autolite. Duane 
Larson and Frank have more detailed scientific info on the subject of 
quality and design and manufacture of the porcelain/ceramic and its porosity 
which contributes to the deposition of fouling deposits on spark plug 
insulators. REGARDLESS of plug brands, if we ran our tractors at 180 degrees 
and under a load at full RPM versus the prolonged slow idle and no load and 
cool operating temperautes at parades, plugs would last muchhhhhhhhh longer. 
Use shutters etc to get them up to temperature,,,,avoid long idle 
periods,,,,,run the hotetst available NON resistor plug,,,,,,,,,dont run the 
carbs any richer then necessary,,,,,,,,,,,keep them well tuned and use wire 
core (not carbon core suppressor wires) plug wire,,,,,and run then loaded 
where possible is my best advice to lessen premature plug fouling.  Ol John
