What would be the best plugs for an "H" on LP?
Thanks

just waiting for the champion/auotolite debate!

If it was a gasoline model, I would recommend the Autolite 3116s, but I think the LP conversion might actually require a colder spark plug? I really don't know.

i looked it up on the autolite chart, the lp would take an autolite 386. here is alink to the spark plug chart, farm tractors are way down near the bottom of the file

My 300 LP had D-15Y's in it when I got it.
When I changed them I went back with the same and she runs like a dream. After 2 months of good use I pulled and checked them, they looked like new.

Looking at the chart it shows the 3116 for gasoline. I am not 100% sure but I thought the LP needed a colder plug. Which is why I went back with the D15 instead of the D21 as recomend.
Hopefully someone with more knowledge on the subject will chime in and answer both our questions.

I use Champion D18Y with no problems. Not sure if the LP plugs are a different part number.
