It's 7 on the heat range... so it is 3 quarters of the way to a cold plug.
If this is a bit cold for gasoline, I think I'll be fine running LP/propane gas with it. LP burns hotter, or so I've read. They even suggested moving one step to a colder plug when switching to LP, so maybe this will do fine.
Anyway, I'll inspect it again in a few months.
Thanks for confirming.
