Great! I have the same, but in worse condition.
Could you tell me the function of that smaller valve?
The bigger is to regulate flame, as I suppose?
The small valve works like the small brass eccentric, of a Coleman suitcase stove. It allows a quanity of air from the tank to the burner to aid in preheat. Once the flame becomes blue and stable the valve is closed, and you pump more air into the fount (tank) to provide the power you need for extended cooking times.
