: : : I don't understand this "Don't use this or that" business. Champion, AC, any name brand plug is as good quality as the next. The problems I've encountered over the past decades have been 1) using the wrong plug for the application, 2) incorrect installation, and 3) something else is wrong.
: : : Remember, these manufactorers didn't last this long by making junk.
: : : In answer to the first question, the number sounds more like an AC than a Champion number (maybe a typo?). Check with your favorite parts store to find a current plug number, by application! Crossing old to new numbers, especially between brands, can be hazardous to ones' health and wealth. I've spent many hours trying to cross-match parts only to find that they don't cross back the same way. : : Champion's are junk. I have had trouble with them in the past. Put AC's in and everything was honkey dory : I have had a lot of problems with champions the last few yeaes.
: If you run with no load they cause problems.
: I use A.C.instead. This why I won't use Champions in my tractors: Last spring while I was shopping for a set to fit my JD4020 (the used equipment dealer had installed very cold LP plugs in a gas tractor), I found this note in the Champion catalog about the D series plugs used in old tractors. "These plugs are equipped with a series gap so they have a hotter spark to fire better in oil." My engine doesn't use oil so that's not a needed modification. But they offer no choice. I bought AC. I won't buy Champion tractor plugs. While this series gap may be a help on an really bad oil pumper its a detriment to a good engine and precisely counter to the work I also did that making a set of plug wires with copper cores and with the connectors soldered to the wires to ELIMINATE the extraneous series gaps of the carbon wires that were on the tractor (and causing intermittant running!). The carbon wires were so bad, it made the 4020 buck in 8th gear moving down the road at 17 mph. That's what I call ROUGH running! Gerald
