In my 1989 JD 316, with the 18hp ONAN, John Deere reccommends an NGK plug. So I bought 2 new NGK's FROM DEERE, and put them in it when I got it 3 years ago. It started kinda hard, ran alright, but dropped a cylinder after a few hours. Plugs looked good, one was fouled, no spark.
So I bought 2 new plugs, put them in, same deal, always started hard, idled rough, and after a few hours dropped a cylinder and popped under load, this time, the other cylinder.
I got the Champion Cross referenced plug, and put 2 in, and so far, 2.5 years, and 200 hours, I have nhad to touch the plugs. It fires right up, often not even needing choke, idles great, plenty of power. Also, this engine has 1500 total hours on it.
Plenty of other situations where an NGK has left me with a dead engine with no warning. Ive had push mowers just shut off and it was a bad NGK plug, never had a champion do that. Also it seems like after a backfire, an NGK is more apt to not function...
Or maybe Im just imagining it? Lots of people seems to like NGK...why, Ill never know.
