Thanks Stan. After running it on 5 for a few days it now lights and runs on lower numbers. Hopefully it was an issue because it hadn’t been lit for awhile. I’ll keep an eye on it.Stan@FourWheel said:Cleaning the burner tube would be my first suggestion.

If they are blocked, even a little, the flame size will be reduced.
There are many helpful videos on YouTube:
