Running the 300 in the cold

Carb is adjusted not running rich but the probablem basically is the 300 doesn't get worked in the winter and while its cold and not mowing season. Not sure it really gets worked in mowing season either but at least it is doing something. Question is for the non-mowing season when all I do is pull a wagon out to the trash pile, or drive it over to the Uncle's to get some stuff and then back (1.5 mile round trip). Would I be better off with a hotter plug like a D21 instead of the 3116s to help with fouling?

First, opinions on what plug to use in your situation will vary like what oil to use.
My opinion. I have 3116's in all my running tractors and have not had to change any plugs in several years. At times they sit for weeks at a time without even being started. At times they are run long enough to move one out of the way to get at another one. I pull the plugs in the spring and clean them when I change oil. I have one H that gets used in the winter for snow removal and we do not get a lot of snow around here. I do some mowing with the Cub and both running H's. They all start right up and run well when I need them.
