Sparkplugs

[Tractor Rod]

I just took the spark plugs out of my cub and two of them were Champion D16’s and the other two were champion D15Y. Which one should I use?
Thanks.

Unless you work your Cub relatively hard, I’d use D21’s. They are a hotter plug and less likely to foul.

Auto lite 3116 are another hotter option. I like them better than champion. JMHO.

Agree with Don. And I like Champions better than Autolite.

Thanks. D21 is what I am going to buy!
