I use the J17Lm (lawn Mower) plug in all my small motors, Pal’s Scout, Ranger, Sea King Midget, 3/4 hp waterwitch, and any motor that requires a short plug because of the motor covers pressing against the spark plug boot.

Tubs, admittedly this confuses me. But, I know that champion recommends the J17LM for my two stroke Toro snowthrowers. In my feeble way of thinking, this plug was meant for four stroke lawnmowers. I would think it would have a cooler heat range than a two stroke plug because it doesn’t need to contend with burning off oil in the combustion process. But who knows, perhaps I am thinking about this all wrong…. Surely never had any fouling issues using the J17LM in my two stroke snow throwers though.
