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

[Ronald L. Cook]

I think you are right, Troy.  My old Champion plugs will work, new will 
not.  I switched to Autolite in my tractors and old Willys.  The 
airplane I had to go to iridium Champions to make it run.  Massive 
electrode Champions seem to cause lots of grief.  Darned unhappy having 
to fork out about $1100 for a set of plugs, too.
