[AJD] JD 70 running rough

[Almost-Running Deere]

Your experince with champions are different than mine.  My snow plow tractor (ford Jubillee) was running rough as heck last January and I changed the points and condensor but it made little difference,  The champion plugs were less than a year old but I replaced them with autolites and the rough running went away.  This has happened on my JD 40 and my A in the last few years as well.  It is easier to get champion plugs but I no longer care for them.  Just my experince.  Dana
